Zinc metal (Zn) reacts with hydrochloric acid (HCI) to produce hydrogen gas (H) and zinc chloride (ZnCl2). A scientist has powdered zinc and a chunk of zinc of equal mass. Available in the lab are dilute HCl and concentrated HCl. Which combination of zinc and acid would react most quickly? Explain why the combination you chose would make the reaction occur most quickly.

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.
