Consider the equation. Which represents the correct mass-volume relationship at STP? 32.00 g of O2 react with an excess of H2 to produce (2 ´ 22.4) L of H2O. 2.00 g of H2 react with an excess of O2 to produce (2 ´ 22.4) L of H2O. 32.00 g of O2 react with an excess of H2 to produce 22.4 L of H2O. (2 ´ 2.00) g of H2 react with an excess of O2 to produce 22.4 L of H2O.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Ais a mountain created from eruptions of lava, ash, rocks, and hot gases.

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.
