The composition of a liquid alcohol mixture to be fed to a distillation tower at 101.32 kPa is as follows: methyl alcohol (xA = 0.30), ethyl alcohol (xB = 0.20) n-propyl alcohol (xC = 0.15), and nbutyl alcohol (xD = 0.35). Calculate the following, assuming that the mixture follows Raoult’s law: a. Boiling point and composition of vapor in equilibrium 1291 b. Dew point and composition of liquid in equilibrium c. Temperature and composition of both phases when 40% of the feed is vaporized in a flash distillation

List four observations that indicate that a chemical reaction may be taking place

What effect might melting sea ice have for people who live in coastal areas?

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.
