Ask These 10 Interview Questions to Impress Your Hiring Manager

Ask These 10 Interview Inquiries to Impress Your Hiring Manager You hear a great deal about what not to state at a meeting nowadays. Be that as it may, ever wonder if there’s anything they’re explicitly searching for you to state? Make sense of how to answer the feared, â€Å"Do you have any inquiries for us?† question easily by thinking about a couple of these diamonds. 1. â€Å"How does this position add to your objectives for this division/company?†Bang! You’re aware of the way that your job will be a piece of a bigger entirety. You’re ground breaking enough to think about how you can contribute. What's more, you’re sufficiently delicate to the company’s objectives to perceive how it fits into their large picture or main concern. Extra focuses on the off chance that you can flip the inquiry: simply name a couple of the objectives for the organization you definitely know line up with this position and afterward ask by what other means a recently recruited employee in that position may cont ribute or quicken that impact?2. â€Å"What do your best recruits typically do in their first month with you?†You’re not simply going to land the position and sluggard into lack of concern. You’re there to kill. This gives you need to get down to business and that you’re anxious to help. As a little something extra, you may get some understanding into the company’s so far obscure quirks.3. â€Å"How would you measure accomplishment in this role?†The meet is really the prime chance to pose this inquiry. Once more, it shows your ground breaking and your longing to exceed expectations and surpass their desires. It likewise gives you an incredible outline for how to render yourself an advantage as fast as conceivable obviously superior to an ambiguous thought of the assignments required and the run of the mill workload.4. â€Å"What late achievements have implied the most to you and your group, and why?†Bonus focuses in the event that you can refer to a portion of these achievements, or have done what's needed examination to state there have been many. This inquiry permits you to flaunt your phenomenal listening aptitudes. Look! It’s not about you! You’re an incredible and liberal partner! Furthermore, individuals love to discuss themselves. It’s an extraordinary icebreaker, in any event, for halfway or nearly right through an interview.5. â€Å"What openings are there for proficient development?†Doesn’t essentially mean you won’t be agreeable or upbeat in the position advertised.

It’s an incredible method to give one final guard of yourself before the choices are made. Also, who knows, you could simply mitigate someone’s concerns enough to make them employ you.10. â€Å"What are a portion of the elusive characteristics of fruitful colleagues here?†You need to recognize what that certain je ne sais quoi may be that helps representatives of this organization exceed expectations. Your questioner may be anxious to discuss the delicate abilities engaged with the activity which are once in a while gotten some information about in interviews. It’s additionally an extraordina ry slippery approach to get a feeling of culture and what the organization will esteem most to check whether you’d be a fortunate or unfortunate fit.

An evaluation of the suitability of the Istisna contract to financing Essay

An assessment of the reasonableness of the Istisna agreement to financing little ventures - Essay Example These banks offer administrations dependent on strict lessons and laws. The banks keep on giving creative budgetary items planned for filling the current holes in the money related industry. These banks have utilized a generous methodology, embraced from Islamic instructing, to offer top notch administrations to clients. One of these methodologies has been the Istisna contract. In view of the Sunnah of the prophet Muhammad (PBUH) this agreement has changed the financial business gigantically (Mahlknecht, 2009). The utilization of this agreement might be tremendously gainful to individuals looking for exhaustive financing for private companies. The agreement and its utilization by Islamic banks The Istisna contract falls under the classification of assembling contracts. It was made by the Islamic Financial Institution in accordance with the Istisna accepts. The agreement is emphatically identified with the shariah. In Arabic, the word Istisna implies making a solicitation to somebody to fabricate, develop or produce something for another. This agreement depends on the rule importance of the word. The agreement, consequently, includes understandings available to be purchased and buy between two people. The things being talked about in the agreement understandings of Istisna are non-existent. This can be named as the best contrast between the Istisna and other monetary agreements inside the business (Warde, 2000). This has prompted the ID of the Istisna as a remarkable deal understanding. Inside the extent of the Istisna contract, the understanding is ordinarily founded on trust between the gatherings. The advantage in the understanding regularly must be built or made in a la ter date. The gatherings typically concur on the date wherein the completed item ought to be conveyed. The way toward making an Istisna contract should be taken care of with significant consideration. The Shariah law directs that a ware planned available to be purchased should in the hands on the vender when the deal is being made (Mahlknecht, 2009). The vender should likewise forces the responsibility for item proposed available to be purchased. An item to be sold should likewise have been increased through worthy methods by the Islamic law. The Istisna contract, nonetheless, appears to offer a marginally unique philosophy. In the Istisna contract, the items being sold are typically, not in their last structure. The center part of the agreement turns into the strict qualities joined to the understanding. All components of the agreement depend on trust and confidence in the capacity of the assembling gathering to convey things. The quality and amount of the item is required to satis fy the settled upon guidelines. In the agreement, the gatherings concur on the particulars of the products to be fabricated just as the date of fulfillment of the assembling procedure. The cost of the things can likewise be another component settled upon by the contracting parties. Every one of these components are done through understandings made by the contracting parties. Inside the extent of the Istisna contract, the Islamic monetary foundations are mentioned by clients to make an item. The item is made by the budgetary organization for the benefit of the client. Endless supply of the development, the item is then conveyed to the client for installment. Trust gets basic as the client will be unable to provide food for the installment of the items conveyed. A significant note to make here is that the agreement terms can't be changed once they have been settled upon. This gets basic in guaranteeing that each gathering conveys its piece of the deal. Disappointment by either party, however, promptly makes the agreement old. The

Is a DUI a Felony or Misdemeanor

Is a DUI a Felony or Misdemeanor Addiction Alcohol Use Drunk Driving Print Are DUIs Felonies or Misdemeanors? By Buddy T facebook twitter Buddy T is an anonymous writer and founding member of the Online Al-Anon Outreach Committee with decades of experience writing about alcoholism. Learn about our editorial policy Buddy T Updated on January 14, 2020 Zigy Kaluzny / The Image Bank / Getty Images More in Addiction Alcohol Use Drunk Driving Binge Drinking Withdrawal and Relapse Children of Alcoholics Addictive Behaviors Drug Use Nicotine Use Coping and Recovery Is driving under the influence of intoxicants (DUI/DWI) a felony or a misdemeanor? Under most circumstances, a first-time conviction for driving under the influence is a misdemeanor, but there are circumstances under which a DUI can be a charged as a felony crime. These circumstances vary by state and jurisdiction. In many states, a drunk driving charge is considered a traffic offense or a misdemeanor, but those charges can be enhanced from standard misdemeanor DUI to felony DUI depending upon other factors.?? Besides the legal implications, being intoxicated beyond the legal limit for driving puts your health at risk in many ways, even if you arent behind the wheel. You will likely undergo an alcohol evaluation to see the extent of your drinking habits and alcohol education to explain how drinking can affect your life and health. 10 Things You Should Know About Getting a DUI Factors That Elevate Misdemeanor DUI to Felony DUI While laws vary state to state, the following are some common situations that can result in a felony DUI. Bodily Harm In most states, if someone is killed or injured by the drunken driver, felony charges can be filed. Its more typical that the driver must be the one who caused the accident that resulted in bodily harm. If you run a stop sign while intoxicated and hit another vehicle, you may be charged with felony DUI if your passengers or people in the other vehicle are injured.?? But it is less likely your charge will be elevated to felony DUI if you were intoxicated but somebody else rear-ended you at a stop sign and you or other people were injured in the accident. Breaking Other Laws and Driving With a Suspended License In some jurisdictions, if you are arrested for DUI while breaking other laws at the same time, the charged can be elevated to a felony level. For example, in some states, if you are driving with a suspended license and are arrested for drunk driving, the offense can be considered a felony. If your license is restricted, suspended, or revoked, it is very bad news to be caught for DUI. Elevated Blood Alcohol Content The standard for impairment is a blood alcohol content (BAC) of .08 percent in all states.?? Some states have also set a level of BAC at which the charge can be elevated to felony DUI. Often, this level is around 0.16 percent.?? In other states, a higher BAC can result in getting a harsher punishment when convicted of misdemeanor DUI. You can expect that the higher your BAC, the worse the penalty will be. Driving DUI with Children in the Vehicle Specific laws have been passed in many states that allow felony DUI charges if there are children in the vehicle. The ages defined may be up into teenage years, such as Leandras Law in New York, which defines a  child as age 15 and younger.?? Prior Convictions for DUI If you have a prior conviction for DUI, states vary in how many convictions and in what period of time these can be used to justify a felony DUI charge. If your driving license privileges have been restricted because of driving under the influence and you are caught driving while intoxicated again, some states will charge you with a felony. For example, if you have been ordered to install an ignition interlock device on your vehicle because of a previous DUI, and you are stopped for drunken driving again, it can be a felony in some states.?? Misdemeanor Maximum of one-year jail time Fines typically $1,000 or less Possibility of probation Felony Minimum of one-year jail time (often in state prison) Fines excess of $1,000 (even tens of thousands) Possibility of parole and probation The Consequences Drunk driving laws vary from state to state and new legislation is passed every year. If you are charged with a felony DUI, youll need a lawyer, who depending on your situation, may try to reduce your sentence or lessen your charges. In some states, however, this may be a waste of time and money as the penalties are mandated by state law and cant be changed.?? In addition to hefty fines and mandatory jail time, if you are charged with a felony DUI you will likely lose the following: Driving privileges (temporarily or permanently)Civil rights (right to vote or own a weapon)Custody or visitation privileges (especially if a child was in the vehicle) Youll also be required to use a monitoring device (breath alcohol ignition interlock device or a blood alcohol continuous monitoring device (SCRAM ankle bracelet). Most states also have laws that require anyone convicted  of drunk driving  to undergo an alcohol evaluation. A counselor will evaluate you to see whether your drinking behavior can be considered alcohol dependence or alcohol abuse. You may be required to enter an alcohol treatment program  or an alcohol education program to learn how binge drinking and other problem drinking can affect your health and life. Do You Know What Drunk Driving Laws Your State Has?

Organizational Culture - 778 Words

Organizational culture influences many aspects of work life. Workplace cultures that are grounded in strong and formally articulated values and modes of behavior define an organization. Well-communicated values influence employee behavior and drive how employees relate with all stakeholders within the organizationÂâ€"from co-workers, management and members of the board to clients, shareholders and the community at large.

Recrystallization of Benzoic Acid Free Essays

Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Recrystallization is a method used to purify compounds, and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteristics are exploited in order to have a crystallization of the desired compound. In this experimented benzoic acid was crystallize using ethanol and water. We will write a custom essay sample on Recrystallization of Benzoic Acid or any similar topic only for you Order Now I chose these solvents based on part C of the experiment (table 1. 1). The compound is too soluble in ethanol but too insoluble in water. Benzoic acid is a polar compound in comparison with ethanol which is a less polar compound. However at low temperatures benzoic acid is insoluble in water. Compounds are soluble in solvents with the same polarity, like dissolves like. Table 1. 1 Benzoic Acid solubility Dissolve Heat Ice H2O No No No Ethanol Yes Yes Yes Hexane No No Acetone Yes Yes Toluene No Yes No The benzoic Acid was dissolved in a very small amount of hot ethanol once dissolved water was added drop wise using a disposable pipet until it got cloudy. Once it reached this point the substance was removed from the steam bed and let cool down at room temperature. It is important to let this cool down slowly so impurities don’t get trapped in between the crystals. After 20 minutes the crystals were filtered out using a vacuum filter method. The crystals were carefully removed from the filter paper and weighted. These crystals were dried out for a period of 2 weeks, to later get a melting point. The MSDS value was compared with the experimental value to verify purity of the crystals Page | 1 Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Data Collected: Ethanol and Water used as solvents Benzoic acid Grams Started 0. 154 Recovered 0. 126 Final Recovered 0. 064 Percent Recovery 81. 81% *Before Drying for two weeks Final Recovery 41. 52% Melting Point 118. 9 ° C – 119. 9 ° C MSDS MP 122. 4 ° C Percent difference 3. 684% Crystallizing benzoic acid using a mixture of solvents is the most efficient procedure compared to using one solvent alone. By comparing the experimental and MSDS melting points we can see that our recovered crystals had very little impurities only a 3. 8 % difference. If I was to repeat the experiment I would improve the recovery process by letting the substance cool down even more slowly to avoid impurities to get trapped in the crystals. When the crystals were moved from the filter paper to the weighing boat some of the crystals were lost. This could be improved by letting the sample dry longer so the crystals would not stick to the filter p aper or the spatula. Another possible error could have happened when taking the melting point, the rate at which the temperature was rising was a little too high. In the future slowly and gradually rising the temperature would give better more accurate results.

Recrystallization was done to remove impurities from the sample. The amount of BA recovered during recrystallization is much less than the extracted amount of BA. We will write a custom essay sample on Recrystallization of Benzoic Acid or any similar topic only for you Order Now The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure samples will have a lower and wider melting point range.The experiment performed was important because it provides important knowledge about the chemical nature and reactivity’s of various compounds that can be used in everyday life. Introduction Now that the desired compound is extracted, it still contains impurities. These impurities can be removed through a process called recrystallization. Recrystallization is a method for purifying solid compounds which are frequently the products of organic reactions. This theory is based on three important concepts. The first is that a compound is always more soluble in hot solvents than in cold solvents.Secondly, molecules have unique solubility properties. Lastly, a growing crystal will only accept similar entities into its lattice. This is related to the crystal lattice theory which states crystal formation is anti-entropic based on the equation ? G =? H-T? S. There are three stages of solubility: collision, dissociation, and solvation. In order to raise the probability of collision between the solute and solvent, heat is added to the system. When this occurs, the solute will attack the crystalline structure of the solute and start dissociation. As dissociation continues until all the molecules are free, solvation occurs.Choosing the right solvent is important when considering recrystallization. The solute must have a high temperature coefficient in the solvent: it must be soluble at high temperatures and insoluble at low temperatures, satisfying the first principle stated above. Also the boiling point of the solvent must be lower than the melting point of the solute. This will ensure that the solute dissolves in the solvent and does not melt. The solvent must also be inert to prevent chemical interactions with the solute. Impurities must either be readily dissolved in the solvent or be insoluble.The solvent must also be volatile, and finally, it would be beneficial to the experimenter if the solvent is relatively inexpensive. Once the color and most impurities are removed, the crystals can be formed in the solution through a process called nucleation. Nucleation can be induced by slowly cooling the solution to room temperature. It is important to do this slowly so that small solute resembling impurities do not enter the crystal lattice, as described by the third principle of recrystallization. Chemists often add already pure crystals of the solute to the solution in order to provide a pre-formed lattice for other molecules to enter. This is called seeding. Scratching the glass container in which the solution is contained with a glass stir rod will also induce nucleation on microscopic glass particles. The concept of scratching is similar to that of seeding. Finally, nucleation can be induced by cooling the solution farther in an ice bath; however, this is only a last resort option due to its least efficiency to bring forth crystals. The crystallized solute can then be collected by vacuum filtration. There is a difference observed in the physical properties of the pure compound and the impure mixture. One of the tests of purity is melting point. Melting point is an intrinsic, or intensive, property; the value is independent of the quantity of the substance. Melting point is the temperature at which a substance changes physical state from solid to liquid. Because the substance will have a certain shape and surface area exposure, there will be a time interval in which the melting occurs. Thus, it is more accurate to refer to this as melting range. Melting range encompasses the temperature at which the first particles can be seen turning from solid to liquid until all the sample is in the liquid state. Purer samples have smaller melting ranges.Perfectly pure compounds will have ranges of only 1-2 °C. Impurities lower melting point below literature values and also widen the range between which melting occurs. New techniques and equipment used were used during both parts of the purification process. Activated charcoal was used to adsorb impure colored products. Gravity filtration was used to remove insoluble products which were impurities. Fluted filter paper was used to catch more of the impurities. A heating mantel was introduced during recrystallization. It is a heat source used for solutions. For determining the melting point of benzoic acid, a Mel-Temp apparatus was use.It is used for determining when a small amount of a solid begins to melt and when the melting ends while recording the temperatures, respectively. Experimental: Recrystallization Lab: Initially, took a small amount of impure BA to the side for following week’s lab. The impure BA crystals were weighed, using an analytical balance, and then placed in a 250 mL Erlenmeyer flask. 200 mL of water was boiled (with boiling stones) in a 250 mL round bottom flask using a heating mantel. The boiled water was added slowly to the benzoic acid crystals. Only enough water was added to dissolve the BA crystals. For the rest of the lab the Erlenmeyer flask was kept on a steam bath. Charcoal was added to the BA solution and then gravity filtered using a funnel with fluted filter paper. The filtrate was collected in a 250 mL Erlenmeyer flask. If color in the BA solution still remained then charcoal should be added again. The BA solution was removed from the steam bath and cooled, preferably on a window sill. If crystals did not form while cooling on window sill, use another method to induce nucleation to the start the formation of crystals. The crystals were collects by vacuum filtration and placed on a watch glass to dry. Melting Point of Benzoic Acid: A melting point tube was loaded with BA crystals by inverting the tube into the BA crystals on the watch glass. The tube was packed by dropping through a funnel. The Mel-Temp apparatus was used to determine the melting point range. A rapid melting range experiment was done first and then a slow melting range experiment was carried out to get a better range. Results: Recrystallization lab: Observations: Not much charcoal was used to adsorb the colored molecules The BA crystals were small, shiny, flaky, and white. Almost comparable to texture of dandruff. Data: Mass of extracted Benzoic Acid = 2. 3 g Mass of recrystallized Benzoic Acid = 1. 84 g Calculations: Percent (%) recovery =(weight after recrystalization)/(mass crude BA) ? 100 Percent (%) recovery =(1. 84 g)/(2. 43 g) ? 100=75. 72% Melting Point lab: Observations: Once the benzoic acid began to melt, it happened very quickly.It was hard was difficult to watch the melting and recording the start and end temperature. The crude BA had a lower and wider melting point range. Data: Melting Point Ranges RunCrude (Impure) Benzoic Acid ( °C)Purified Benzoic Acid ( °C) Fast 110. 2-118. 4 at 4. 5 selectivity (Range: 8. 2)115. 4-118. 5 at 4 selectivity(Range: 3. ) Slow113. 2-117. 3 selectivity (Range:4. 1)117. 5-120. 0 selectivity (Range: 2. 5) Discussion ; The goal of recrystallization and determining melting point labs were to explore the techniques used to obtain pure samples from desired compounds. After the extraction the goal was to recrystallize the benzoic acid and determine the percent recovery. Then the goal was to determine the melting point range of the recrystallized benzoic acid and compare it to the melting range of the small sample of the impure benzoic acid. 1. 84 grams of pure benzoic acid was obtained, which was calculated to be 75. 2% from the 2. 43 grams of impure benzoic acid.The percent recovery from the impure sample shows that about three fourths of the sample was able to be collected as pure benzoic acid, and that 0. 59 g of the impure benzoic acid was impurities. From this the experimenter can infer that the pure benzoic acid accounted for most of the mass or that little benzoic acid was lost with the removal of the impurities. Also, there is always a chance that some of the benzoic acid may have remained in the solution instead of crystallizing. Also, using an ice-bath to induce nucleation could have lowered my results or recrystallization because it was the last resort to crystalize the solute. Maybe adding too much charcoal could have adsorbed some of the solute. The charcoal was used to adsorb any of the cellulose (which is the reason for the color) that was left behind. Not too much charcoal was actually used; however, my benzoic acid solution did not have much color so charcoal may not have been needed. Note that the initial value for percent recovery is slightly less than the extracted mass because of the impure benzoic acid set aside for the melting point comparison. The total composition from the very first starting benzoic acid mixture is only 44. 2% (1. 84 grams / 4. 17 grams). Considering practical purposes of recrystallization, one comes to realize how important it is to make this processes as efficient as possible to save money and gain as much product as possible, for example with ibuprofen purification for the pharmaceutical industry. The purity of the sample is shown by the melting range. As expected, the pure benzoic acid had the smallest melting point range of 2. 5 °C. From this, one can tell that this sample was not perfectly pure because pure compounds have melting point ranges of less than 1 °C.There may have been some impurities left in the sample since activated charcoal was not used for this sample. Human error while scraping the impure mixture from the funnel and also from the Erlenmeyer flask would result in a decreased yield. Also, the nucleation may have had some impurity particles collect in the lattice when recrystallizing. After performing the rapid and slow experiment, the temperatures (especially for the pure BA) were not similar. This was probably due to what is called thermometer lag. If the Mel-Temp apparatus’ selectivity was higher than the temperature readings were not as accurate as the slow experiment.The actual value for the melting range coincides with the literature value of 122. 4 °C given in the reagent table. The impure sample, however, had a significantly larger melting range of 4. 1 °C. Also, the impure sample had a lower temperature. This is because impurities disrupt lattice forces and decrease the energy required to break the intermolecular bonds between benzoic acid molecules. One way that this experiment could have been improved is to have more space to perform the various steps in the lab. A lot of the mistakes and errors committed (i. e. pillage) were due to crowding of various equipment that were closely packed next to each other. Overall, theses labs were a success be the experimenter was able to achieve the goals of each lab. The benzoic acid was able to recrystallize and the melting point was fairly close to the literature value even with possible errors performed in lab. Works Cited Wikipedia: The Free Encyclopedia.

How to cite Recrystallization of Benzoic Acid, Papers Recrystallization of Benzoic Acid Free Essays Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals, recrystallization, takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

When the product of that reaction is treated with hydrochloric acid, benzoic acid is formed. From the balanced chemical equation, it is clear that the benzoic acid will not be pure since the byproduct MgClBr, an ionic solid, forms at the same time the desired product forms. Benzoic acid can be separated from ionic solids because the materials have different solubilities in water. At room temperature, benzoic acid is not particularly soluble in water, whereas ionic solids like MgClBr are. Thus, adding water to the crude reaction products will dissolve the ionic solid, and nearly all of the benzoic acid will remain undissolved. If the suspension were filtered, much of the impurity would be washed away; however, the resulting product wouldn’t be as pure as a recrystallized product. To take advantage of the extra purity garnered by crystallization, all of the benzoic acid must be dissolved. On the other hand, the benzoic acid needs to come back out of solution to crystallize. Simply adding room-temperature water cannot accomplish this goal; once the benzoic acid is dissolved there would be no reason for it crystallize. Since benzoic acid is much more soluble in hot water as compared to cold, small amounts of hot water are added to dissolve the benzoic acid. If the hot, saturated, aqueous solution of benzoic acid is cooled, the solution becomes supersaturated, and the supersaturated solution crystallizes. Procedure 1. Obtain a sample of copper(II) sulfate contaminated benzoic acid. 2. Add approximately 0. g (record the actual mass) of the contaminated benzoic acid and 5 mL of water to a 25-mL Erlenmeyer flask. 3. Warm the flask and its contents on a hot plate and slowly add near-boiling water to dissolve the solids. 4. Continue to warm the flask and add near-boiling water until all of the solids have disolved 5. Remove the flask from the hot plate and allow it to cool slowly on the bench top. Covering the flask with a beaker can help slow the rate at which the solution cools. After approximately twenty minutes, crystals will have formed. Cool the suspension further using an ice bath. If crystals have not formed after 20 minutes, there are a few techniques that can be used to coax the crystals out of solution. Often scratching the glass container with a glass rod will induce crystallization. Alternatively, a seed crystal can be obtained by evaporating a drop of the solution on the tip of a stirring rod or spatula. Returning this seed crystal to the super saturated solution will cause crystals to form. 6. Transfer the crystals to a Hirsch funnel, and filter the benzoic acid–water suspension. . Wash the benzoic acid crystals with ice-cold water by pouring ice-cold water over the crystals. 8. Dry the crystals on the Hirsch funnel; that is, allow the vacuum filtration system to draw air through the crystals until the mass of the crystals remains relatively constant. Place the benzoic acid in your drawer and allow it to dry completely. 9. While the benzoic acid is drying, evaporate the water from the aqueous CuSO4 s olution. Remember to add a magnetic stir bar to your flask to lower the risk of spattering. 10. Note the appearance of your CuSO4, and, if possible, record the mass of the CuSO4 that you obtained. 11. After allowing the benzoic acid crystals to dry for a week, determine the mass and the melting point of the benzoic acid. Experimental Report Write an â€Å"experimental† describing the procedure that you followed to recrystallize the benzoic acid. A first draft of the experimental is due one week after steps 1–10 have been completed. A final copy that includes the final mass and the melting point of the benzoic acid is due one week after step 11 is completed. How to cite Recrystallization of Benzoic Acid, Papers

The Attempted Robbery Essay Example

The Attempted Robbery Essay It was past midnight. Suddenly there was a knock on the door. I quickly switched on the lights. My instincts told me something was wrong. My mind quickly flew to my parents, who are currently at Grandmas to settle some urgent family matters. Could something have happened to them? Is it the police who are knocking on my door? My palm quickly started to sweat with worry. My nose suddenly picked up a smell; it was an overpowering smell of beer. My heart thumped repeatedly like horse hooves on a dirt road, giving signals to my brain to not open the door. I knew then, it was a premonition of fear and danger. But my curiosity took over any sense that I ever had. True enough, my caution was justified, for when I opened the door, two tall brooding men about 6 feet high stood in front me. They looked too drunk to stay still, as if they were wearing some slippery boots. I couldnt make out their faces because it was too dark but I didnt need to see their faces to know that they were men I should not cross. I kindly asked them to leave, but they continue to be in their drunken stupor and ignored me. They slurred swearing words towards me and my patience quickly trickled to an end and my anger rising to its peak.

I screamed to them quite rudely to leave, but I regretted at once the words that I had just then uttered. As if in reply to my rude screaming, the two men started to shout obscenities at me. Then all of a sudden, something sharp glistened in the dark coming from one of the mens hand. It was a knife. I gulped in fear and judging from his strong muscles, he was indeed very strong. My brain screamed in panic and little beads of sweat formed on my forehead. I went numb with thought, and stood frozen in front of the now two menacing men. The knife-man lunged and as quick as a bolt of lightning he had the point of his knife at my throat. I was wild with increasing fear and the feeling threatened to crush me down to a collapse. My face paled to ghastly whiteness and my heart pounded like the thrumming wings of a caged bird. I continue to stand there as if I was a monument frozen for eternity. I was stunned by all the suddenness of the events and before I knew it, I was held in a vice-like grip by the other man. My heartbeat continued to thrum crazily against my ribcage and I hawked, my throat dry with fear. Reluctantly, I lead them to the drawer where my mum keeps her jewellery. I dread to think of how my mum would react after she finds out all her missing valuables that amount to thousands of dollars. The knife-man leaned over and made a grab for the trinkets. The other man momentarily forgot about me and went aside to the knife-man to also greedily swoon over all the glittery bracelets and necklaces. With sudden courage, I lifted my right hand to come down hard over the back of the knife-man. The force of the blow succeeded in taking the man right down to hit the bedside table. There was a sickening thud as the head banged against the sturdy and hard surface of the table. He was severely injured with blood covering his face and lashes of cuts from the sharp point of the table. He was dropped unconscious. The other man screamed in rage and charged towards me and with quick swiftness I grabbed the perfume on the bedside table and sprayed it into his eyes. He shrieked in fury and agony and temporarily blind, started to sightlessly grab me. I again took upon the chance to seize the chair near the work table and broke it over the mans head. He fell down, statically still. He was dead. Twenty minutes flew by and the police were already herding the then unconscious (now conscious) man into the police car. My parents were back and were alerted with the frightening experience that I had just gone through. Though still shaken, I tried my best to give my statement to the police. My parents were dumbfounded when I told them in detail what had just happened, but when I finished, they smiled and expressed relief that I was not injured. All was well.
