If a 1.85 g mass of zinc produces 475 ml of gas and your balloon weighs 0.576 g and the room temperature is 18.5°c. calculate the amount of zinc needed to produce enough gas to get your balloon airborne by adding 1 ml to the required balloon volume so that its density is less than that of the surrounding air.

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.
