A75.0 g piece of gold at 650. k is dropped into 180. g of h2o(l) at 310. k in an insulated container at 1 bar pres- sure. calculate the temperature of the system once equilib- rium has been reached. assume that cp, m for au and h2o is constant at their values for 298 k throughout the temperature range of interest.

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

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.
