Skunks have several molecules that make their spray smell absolutely terrible to most animals. One chemical in skunk spray is called 2-butene- 1-thiol, and it has a molecular weight of 88 grams per mole. We'll call this one compound "B" for short. Another skunk scent molecule is 2-quinolinemethanethiol, which has a molecular weight of 175 grams per mole. We'll call this one compound "Q" for short. If a skunk walked by your window at night, and let out a quick little spray, which compound would you smell first, compound B or compound Q? Explain your answer.

2. The Anemovax COVID-19 vaccine uses 0.950% (w/v) NaCl (normal saline, preservative- free) as its diluent. After removing from the freezer or refrigerator, the vaccine must be mixed with the diluent before administration. It is diluted to a total volume of 10.0 mL, and each vial contains eight doses. a. Calculate the mass (in grams) of NaCl that is needed in order to prepare a total of 10,000 doses of the vaccine. b. Express the concentration of the vaccine diluent in molarity. (MW = 58.44 g/mol) One vial of Anovax vaccine contains an unknown mass of vaccine dose. It was diluted to 20.0 mL. A 25.0-µL aliquot was taken and was further diluted to 2.00 mL. Another 1.00- mL aliquot was taken and was diluted to 1.8 mL. Finally, this 1.8mL was found to have enough vaccine for five 20-ug doses of vaccine. c. How many milligrams of Anovax vaccine is present in the first vial?
Sulfur compounds cause "off odors" in wine, so winemakers want to know the odor threshold — the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 2525 micrograms per liter of wine (?g/L).(�g/L). The untrained noses of consumers may be less sensitive, however. The DMS odor thresholds for 1010 untrained students are given. DMS odor thresholds 30 30 42 35 22 33 31 29 19 23 Assume that the standard deviation of the odor threshold for untrained noses is known to be ?=7 ?g/L. Give a 95% confidence interval for the mean DMS odor threshold among all students. Use the four‑step process. Give your answer as an interval in the form (lower bound, upper bound). Give your numbers to two decimal places. What is the confidence interval ?
Apple cinnamon Glade air freshener has two fragrance molecules in it. The 'apple' molecule has a molecular weight of 400 grams per mole, while the 'cinnamon' molecule has a molecular weight of 170 grams per mole. You're sitting at the back of the room and have an extremely sensitive nose. If I sprayed apple cinnamon Glade air freshener at the opposite side of the room, which scent would you smell first? Explain your answer.

sk: The Chemistry of Respiration Quantities 2. Examine the two scenarios belowoi6g • Scenario A: 100 g of glucose in the presence of unlimited oxygen is metabolized through aerobic respiration. • Scenario B: 100 g of glucose in the absence of oxygen is metabolized through anaerobic respiration. Would the mass of products produced in Scenario A be greater than, less than, or equal to the mass of products produced in Scenario B? Justify your answer.
pour it 2. Still sleepy from a late night studying, you take the milk out of the refrigerator and pour it on your lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation for the fact of coagulated milk onto your cereal. The last time you saw milk coagulate like that was when you added breakfast cereal. Unfortunately, by the time you notice the funny smell you have already poured clumps lemon juice to milk to make paneer (fresh cheese). As a group, craft a chemical explanation foea added that spoiled milk coagulates.
4. Two engineers are serving as trainees in a laboratory of a pharmaceutical company. One of their tasks involves determining the identity of a vitamin they were given by using any equipment or method at their disposal. As a hint, their supervisor gave them a list of possible candidates for the vitamins identity which includes: Vitamin Molecular Formula Folinic Acid C20 H23 N707 C3H11NO3 C,H,N20 C17H20N406 Pyridoxine Niacinamide Riboflavin To identify the vitamins identity, the two trainees separated their sample into two equal portions and performed two separate tests: [a.] Engr. Mayo used the flame atomic absorption spectrophotometer in order to identify the elemental composition of the sample which happens to be 59.0% C, 5.0% H and 22.9% N by mass [b.] Engr. Busog on the other hand mixed his 3.88 g sample with 30.0 mL of nitrobenzene, C,H5NO2 (Latent Heat of Fusion = 79.81 J/g). Using Beckmann's method, he determined the freezing point depression to be 7.1 deg C. Based on the tests…
