The depletion of ozone (O) in the stratosphere has been a matter of great concern among scientists in recent years. It is believed that ozone can react with nitric oxide
(NO) that is discharged from high altitude planes. The reaction is
0, + NO → 0, +NO,
If 7.40 g of O, reacts with 0.670 g of NO,
a)
b)
Which compound will be the limiting reagent?
How many grams of NO, will be produced?
Calculate the number of moles of the excess reagent remaining at the end
of the reaction.

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.
