The chemical equation for the reaction observed in the “Foiled Again” demonstration is shown below: 2 Al(s) + 3 CuCl2(aq) → 2 AlCl3(aq) + 3 Cu(s) a) Rewrite the chemical equation as a statement using words instead of symbols. b) Water is present during this reaction, but it is not written as a reactant or product. How does the chemical equation indicate that water is present?
