The

Ba (OH)_{2} + 2 N H_{4} Cl \to BaC l_{3} + 2 N H_{3} + 2 H_{2} O

reaction is an example of double displacement reaction and endothermic reaction.
Endothermic reactions are chemical reactions where the reactants absorb the heat from the environment to produce products. These reactions form a cooling effect by lowering the temperature of the surrounding area.
On the other side, reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions. In double replacement reactions, the positive ions exchange with the negative ions. The same process occurs in this reaction. So, the reaction of ammonium chloride and barium hydroxide is an endothermic and also a double displacement reaction.
The reaction is:

Ba (OH)_{2} + 2 N H_{4} Cl \to BaC l_{3} + 2 N H_{3} + 2 H_{2} O

In this reaction, ammonium chloride is slightly acidic and barium hydroxide is very basic, for that reason we get an acid-base reaction. This reaction is used to recover the ammonia in the preparation of sodium carbonate from sodium chloride.
