2.) You have just volunteered to decorate the gym for the winter dance with 300.0 Helium balloons. Their is a store in town that will rent a 25 L. helium tank with a
pressure of 30.0 atm. Each balloon, when filled, holds 2.5 L of helium gas at a pressure of
1.04 atm. Will one tank be enough to fill all 300.0 balloons? Assume that the gas
temperature does not change as the balloons are filled. If not, how many balloons can be
filled with the tank of gas?

Part 1: include important facts found through your research. part 2: include your visual display. include your summary of “the chemistry of water” from the national science foundation website. include your experiment. part 3: include responses to the reflection questions.

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.

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
