In a calorimeter 72.55 g of an unknown metal at 71.6 °C is added to 58.85 g of water at 22.4 °C. After stirring and waiting for the system to reach equilibrium, the final temperature reached 47.3 °C. Calculate the specific heat of the metal. (The specific heat of water is 4.184 j/g 0C).

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.
