Expert Answer:

When Barium Hydroxide (Ba(OH)2) reacts with ammonium chloride (NH4Cl), Barium Chloride (BaCl2) and Ammonium Hydroxide (NH4OH) are formed as products, which implies that it is a double displacement reaction, as per the following reaction: 

2 NH4Cl + Ba(OH)2 ? BaCl2 + 2 NH4OH

The Ammonium Hydroxide (NH4OH) formed decomposes to give, Ammonia (NH3) and Water (H2O), according to the following reaction:

2 NH4Cl + Ba(OH)2 ? BaCl2 + 2 NH3 + 2 H2O
