A metal ' M ' reacts with nitrogen gas to afford ' $\displaystyle \mathrm{M}_3 \mathrm{~N}^{\prime} .{ }^{\prime} \mathrm{M}_3 \mathrm{~N}^{\prime}$ on heating at high temperature gives back 'M' and on reaction with water produces a gas 'B'. Gas 'B' reacts with aqueous solution of $\displaystyle \mathrm{CuSO}_4$ to form a deep blue compound. 'M' and 'B' respectively are :
