1. Use this chemical equation to answer the following questions: 4 Na + 02 > 2 Na, o

a) How many moles of sodium (Na) would be needed to react with 3.82 moles of oxygen (O.)?

b) How many moles of Na, o can be produced from 13.5 moles Na?

c) How many moles of O, are needed to produce 34.7 g of Nao?

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.

How many moles of sulfur dioxide are produced when 4.38 moles of oxygen completely react with iron (iv) sulfide
