Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ Ca(NH)+2H_2O\xrightarrow{{}} $ $ Ca{{(OH)}_2}+\underset{[B]}{\mathop{NH_3}}(g) $
$ \underset{[B]}{\mathop{2NH_3}}+3CaOCl_2\xrightarrow{{}} $ $ \underset{[C]}{\mathop{N_2}}(g)+3CaCl_2+3H_2O $
$ \underset{[C]}{\mathop{N_2}}(g)+3Mg\xrightarrow{{}}\underset{[D]}{\mathop{Mg_3N_2}} $
$ \underset{[D]}{\mathop{Mg_3N_2}}+6H_2O\xrightarrow{{}}3Mg{{(OH)}_2}+\underset{[B]}{\mathop{NH_3}} $
