Question

Write the equations for the following reactions, which result in the formation of ammonia:
(i) a mixture of ammonium chloride and slaked lime is heated.
(ii) aluminium nitride and water.

Answer 1

The required equations are:

1. $2{\mathrm{NH}}_4\mathrm{Cl}+\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\stackrel{∆}{\to }{\mathrm{CaCl}}_2+2{\mathrm{H}}_2\mathrm{O}+2{\mathrm{NH}}_3$
2. $\mathrm{AlN}+3{\mathrm{H}}_2\mathrm{O}\to \mathrm{Al}{\left(\mathrm{OH}\right)}_3+{\mathrm{NH}}_3$
