For each of the following reactions, identify which reactant is the Lewis acid. Select 1 if the first listed reactant is the Lewis acid or 2 if the second listed reactant is the Lewis acid. 1)Zn2+ + 4NH3-----> Zn(NH3) 2) H+ + H2O----> H3O+ 3)2NH3 + Ag+-----> Ag(NH3)2+ 4)SO2 + CaO ------>CaSO3 pls show me how and the answer by stating which 1 or 2 for each equation:)
