Spare Parts In the United States‚ drinking and driving is a major concern in today’s society as about thirty-two percent of total traffic deaths involve alcohol (Hanson). To prevent people from driving under the influence‚ many slogans and advertisements are used mainly to encourage driving carefully. One advertisement made by the car manufacturer BMW is found in Public Interest Magazine and promotes safe driving with the message “Don’t Drink and Drive.” The visual in this advertisement is a bare

Where We Were The prohibition was a movement from a women’s christian organization back in 1920 that induced the 18th amendment to be approved and put into effect. While the amendment generally worked in the first few years‚ after some time‚ it began to dissolve and break down in the eyes of the citizens. People rebelled and drank liquor anyway as well as lowering respect for other’s view point on religion. For that reason‚ the Prohibition never became what it was supposed to be. Between beer‚

This experiment involved a substitution reaction to perform synthesis of 2-phenylethanol to get (2-bromoethyl)benzene. Using NaBr in an acidic solvent of H2SO4 with H2O present‚ this synthesis was possible. Subsequent evaluations using TLC and then analyzed samples by Gas Chromatography were done to evaluate the results. Using SN2 reactions‚ primary alcohol is going to be converted to alkyl halide. Since the reaction can be reversed‚ the strong sulfuric acid was to make sure the product would indeed

The purpose of this lab was to use a spectrophotometer to find the concentrations of glucose in varying samples of Gatorade. The varying executions included changing the temperature of reaction (room temperature instead of 40 degrees centigrade)‚ changing the time for reaction (20 minutes in the water instead of 45 minutes)‚ and changing the amount of enzyme added (0.1mL of enzyme. The results in from this lab gave data points with respect to ferricyanide. Fortunately‚ ferricyancide and glucose have

During the prohibition era‚ alcohol was seen as the reason for problems in society and within families. Prohibition was enacted as it was believed it would help solve societal issues such as crime‚ poverty and violence. Nearly 80 percent of U.S. Congress members violated prohibition laws themselves at that time. George Cassidy‚ whom was also known as “Man in the Green Hat”‚ reports he made up to 25 daily deliveries to Capitol Hill. He was arrested‚ plead guilty and started selling alcohol in

Small samples of acetaminophen‚ acetylsalicylic acid‚ cellulose‚ starch‚ and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water‚ acetone‚ or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next‚ four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle. The grinded up pills were then weighed. The grinded

Following standard procedures and using the resulting aldehyde‚ along with 2‚4-dimethylpyrole‚ a BODIPY dye was obtained [36]. To facilitate intersystem crossing‚ the 2- and 6- positions of the boradiazaindacene ring system were iodinated

Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.
