A chemistry Lab- incharge kept Zn metal in FeSO_4 solution and observed that after some time green FeSO_4 solution turn to colourless and some brown powder was deposited on zinc. In the above section, zn metal acted as

A metal ‘M’ reacts with nitrogen gas to afford 'M_(3)N' . 'M_(3)N' on heating at high temperature gives back ‘M’ and on reaction with water produces a gas ‘B’. Gas ‘B’ reacts with aqueous solution of CuSO_(4) to form a deep blue compound. ‘M’ and ‘B’ respectively are :
