1. The document provides the molecular, total ionic, and net ionic equations for 4 metathesis reactions involving ammonium chloride and sodium hydroxide, lead nitrate and sulfuric acid, nickel chloride and sodium carbonate, and nickel chloride and silver nitrate. 2. For each reaction, the molecular equation shows the complete chemical formulae, the total ionic equation shows the dissociated ionic species, and the net ionic equation shows only the spectator ions that are not involved in the reaction. 3. The net ionic equations are NH4+ + OH- → H2O + NH3, Pb2+ + SO42- → PbSO4, Ni
