Which of the following equations is balanced correctly and has the correct products for the reactants rbno3 and bef2? 3rbno3 + 3bef2 → be(no3)3 + 3rbf, because be increases in charge from 2+ to 3+ when it is replaced 2rbno3 + bef2 → be(no3)2 + 2rbf, because be keeps a 2+ charge throughout the reaction rbno3 + bef2 → beno3 + rbf2, because be keeps a 1+ charge throughout the reaction 2rbno3 + bef2 → be(no3)2 + 2rbf, because be increases in charge from 1+ to 2+ when it is replaced

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.
