1) you are asked to make 10 miles of iron (fe) from iron oxide (fe2o3) and excess carbon monoxide (co). fe2o3(s) + 3co(g)—> 2fe(l) + 3o2(g). how many moles of iron oxide must you use.

a) 3 moles
b) 2 moles
c) 10 moles
d) 5 moles

2) 2c4h10 + 13o2–> 8co2 + 10h2o. if i want to produce 50g of h2o using the above combustion reaction, how many mol of c4h10 should i use?

a) 0.55 mol c4h10
b) 10 mol c4h10
c) 2.77 mol c4h10
d) 3.79 mol c4h10

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.
