- 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 ?Correlate the importance of the parts of a fragrance and their characteristics, which physical attribute of the fragrant note is essential and why ?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. (Fun fact: the only predator of the skunk is the Great Horned Owl - I guess it can't smell a skunk!)

- Pre what will be observed in each experiment below. predicted observation (choose one) experiment Can A will make a louder and stronger fizz than can B. A student has two unopened 33 cL cans containing carbonated water. Can A has been stored in the garage (32°C) and can B has been stored in the fridge (8 °C). The student opens one can at the time, both cans make a fizz. Can B will make a louder and stronger fizz than can A. The fizz will be the same for both cans. There is not enough information to predict which can will make the louder fizz. The bubbles will shrink, and some may vanish. A student sees tiny bubbles clinging to the inside of an unopened plastic bottle full of carbonated soft drink. The student opens the bottle, and hears a loud hiss as gas under pressure escapes from the bottle. The bubbles will grow, and more may appear. The bubbles won't change. I need more information to predict what will happen to the bubbles.The active ingredient of Benadryl© Chesty Forte Cough Liquid is Guaiphenesin anexpectorant drug used to assist the expectoration ('bringing up') of phlegm from theairways in acute respiratory tract infections.
