- Tom, an analytical chemist, bought a bag of decaffeinated coffee from a grocery store. However,Tom suspected that he might have received regular coffee and therefore decided to analyze hiscoffee for caffeine. In the lab, he took 0.5 mL of the brewed coffee and diluted it in water tomake a 100.0 mL solution. He performed four analyses and found the concentrations to be 4.69,3.99, 4.12, and 4.50 mg/L, respectively. (Assume the density of all solutions is 1.000 g/mL,1oz= 28.35 mL).(a) Report the concentration (in mg/L) of caffeine in the brewed coffee using the format asaverage ± standard deviation. (Note this is not the concentration in the diluted solution.)(b) Look up the caffeine content of regular vs. decaffeinated coffee. Do you think that Tom wasgiven the wrong type of coffee?(c) Caffeine intake of 300 mg per day reportedly has no adverse effects in the vast majority ofthe adult population. If Tom drinks 3 cups (8 oz/cup) of this coffee daily, is his intake withinthis known safe…Figure 3 shows a substitution reaction between triphenylmethyl chloride and an excess of the base methanamine.

[Round the answer to three decimal places. Do not type in the unit. Use a decimal point.] * Do you need to add imidazole to the reaction mixture used in this question to absorb the hydrogen chloride gas produced during the reaction?If the reaction mixture containing p-aminophenol, distilled H2O, and acetic anhydride was heated to 200 degrees celsius what would have happened? (How is it different from 100 degrees celsius? I am unsure...) Thanks XOXOX ??
- Question 1 You are employed as a co-op student at the Drug and Alcohol Testing Association of Canada (DATAC) developing analytical tests for sports doping agents. You are asked to prepare a procedure for the extraction of methylphenidate, the active compound in Ritalin, from urine samples (consider them as simple aqueous layers, you do not need to consider other components!). The goal of the procedure is to extract the methylphenidate into an organic layer which will then be evaporated and the residue will be tested for the drug. You find that methylphenidate is highly soluble in 2-methyltetrahydrofuran, a bio-renewable solvent. Draw the structure of 2-methyltetrahydrofuran and give two reasons why it is a good solvent choice for liquid-liquid extraction. (Please find the image attached below to help you with this question) Question 2 (cont. from scenario 1). Your colleague is helping you develop the urine test. They suggest that the urine should be adjusted to a pH above 7 before…Let's imagine that in a drug design project a problem is encountered with the low water solubility of a lead compound. The compound has the low melting point of 41-43°C, and a log P value of 4.95. The compound does not possess any ionizable basic or acidic functional groups. Suggest two kinds of modification that the design team could introduce to increase the water solubility of the lead compound. Modification 1: Modification 2:Heat the reaction mixture, (p-aminophenol, distilled H2O, and acetic anhydride). with stirring, directly on a hot plate, using a thermometer to monitor the internal temperature (about 100°C). After the solid has dissolved (it may dissolve, precipitate, and redissolve), heat the mixture for an additional 10 minutes at about 100°C to complete the reaction. (Final product crude Acetaminophen) <--What if the following was heated to 200 °C instead?
- Before combining the oil and water phases when making moisturising lotion, the emulsifiers (Glyceryl stereate and Polysorbate 80) must be dissolved in either the oil or the water phase depending on their solubility properties. Decide in which phase each or both the emulsifiers must be dissolved and What type of emulsion (o/w or w/o) will this formulation form? Give a reason for your answer.Write an equation for the rapid reaction (call this reaction 1) that occurs when aspirin (an acid) dissolves in sodium hydroxide (a base) solution.
