Miners discover a new vein of metal in the mine they are excavating. They send a sample to your lab so you can determine what type of metal it is. You heat up a 2 kg block of the unknown metal from room temperature of 298 K until it melts at 1768 K. You measure that it takes 1.24 x 10^6 J of energy to melt the block. Use the specific heats of various metals shown below to determine what metal the miners have discovered.

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.
