Homework - Unanswered When 0.107 g of Zn(s) combines with 56.4 mL of HCl(ag) in a coffee cup calorimeter, all of the zinc reacts, which increases the
temperature of the HCl solution from 23.2 °C to 24.8 °C:
Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
Calculate the enthalpy change of the reaction Arxn in J/mol. (Assume the volume of the solution doesn't change, density of the
solution is 1.00 g/mL and the specific heat capacity of solution is 4.184 J/gºC.)

Asolution contains 225 g of sodium chloride, nacl, dissolved in enough water to make a 0.25 l of solution. what is the molarity of the solution?

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.

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.
