The human microbiome is one of the major frontiers of current scientific investigation. Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?

Discuss some applications of simple distillation and steam distillation. Explain why you can use each method for the chosen application. What is the most dominant intermolecular forces of attraction that exist between: a. water and limonene, the major monoterpene component of lemon essential oil? b. water and constituent ions of sodium chloride? 6. Based on your answers in number 5, which pair (water-limonene or water-sodium chloride) exhibits a stronger attraction between their molecules/ions? 7. Describe what happens during the salting-out process in terms of the intermolecular forces of attraction involved as mentioned in your previous answers.
Rubbing alcohol is often used as a disinfectant and sometimes as a component of handsanitizers. If you were to purchase a bottle of rubbing alcohol at a store, it would most likely sayisopropyl alcohol or isopropyl rubbing alcohol, although it is also called isopropanol. Ethylalcohol is also used in hand sanitizers, and is actually more commonly used. Why would a handsanitizer whose major component is ethyl alcohol evaporate more quickly than one whose majorcomponent is rubbing alcohol?
