The balanced molecular and net ionic equations for each of the following neutralization reactions are:
(a) Aqueous acetic acid (HC2H3O2) is neutralized by aqueous barium hydroxide.
2HC2H3O2 + Ba(OH)2 -> Ba(CH3COO)2 + 2H2O
(b) Solid chromium(III) hydroxide reacts with nitrous acid.
Cr(OH)3 + 3HNO2 -> Cr(NO2)3 + 3H2O
(c) Aqueous nitric acid and aqueous ammonia react.
HNO3 + NH3 -> NH4+ + NO3-
