The ionic equations represent the reactions between four metals, p, q, r and s, and solutions of the salts of the same metals

p + q2+ -> no reaction
r + p2+ -> r2+ + p
q + s2+ -> q2+ + s
s + p2+ -> s2+ + p
s + r2+ -> s2+ + r
s + q2+ -> no reaction

what is the correct order of reactivity of the metals?

most > least
a. p r s q
b. q r s p
c. q s r p
d. s q p r

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.

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction
