A 3.81-gram sample of NaHCO 3 was completely decomposed in an experiment. 2NaHCO 3 Na 2 CO 3 +H 2 CO 3 In this experiment, carbon dioxide and water vapors combine to form H 2 CO 3 . After decomposition, the Na 2 CO 3 had a mass of 2.86 grams. Determine the mass of the H 2 OO 3 produced . B. Calculate the percentage yield of H 2 CO 3 for the reaction Show your work or describe the calculation process in detail.

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.
