What is the final temperature of a system if 13.00 g of gold at 90.0°c is placed in 13.00 g of water at 26.00°c? the molar heat capacity of gold is 25.41 j/(mol · °c) and the heat capacity of water is 4.18 j/(g · °c).

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.
