Iron-reducing bacteria can be used for the production of ferrous (Fe2 ) ions from hematite iron ore (Fe2O3) as electron acceptor and agricultural waste cellulose (C6H10O5) as electron donor. Write a balanced redox equation to describe the reaction

As air becomes more dense, (select all that apply) o. air weighs less o. gas molecules are closer together o. air is colder o. air weighs more o. gas molecules are further apart o. air is hotter

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.

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?
