$\text{P}+{\text{N}}_{\text{2}}\to \text{nitride(Q)}\stackrel{{\text{H}}_2\text{O}}{\to }{\text{NH}}_{\text{3}}+{\text{CuSO}}_{\text{4}}\to$Blue-violet coloured sol.
$\underset{\left(\text{P}\right)}{\text{3}\text{Mg}}\text{+}{\text{N}}_{\text{2}}\to \underset{\left(\text{Q}\right)}{{\text{Mg}}_{\text{3}}{\text{N}}_{\text{2}}}\stackrel{{\text{H}}_{\text{2}}\text{O}}{\to }{\text{Mg(OH)}}_{\text{2}}\text{+}{\text{NH}}_{\text{3}}$
Hence$\text{P}$and$\text{Q}$are$\text{Mg}$and$\text{M}{\text{g}}_3{\mathrm{N}}_2$respectively.
