Question

Calcium amide on hydrolysis will give gas (B) which on oxidation by bleaching powder given gas (C). Gas (C) on reaction with magnesium gives compound (D). (D) on hydrolysis gives again gas (B). (B), (C) and (D) are:

• A. ${NH}_3,N_2,{Mg}_3{N}_2$
• B. $N_2,N{H}_3,MgNH$
• C. $N_2,N_2{O}_5,Mg{\left({NO}_3\right)}_2$
• D. ${NH}_3,{NO}_2,Mg{\left(N{O}_2\right)}_2$

Answer 1

Answer: (A)

${NH}_3,N_2,{Mg}_3{N}_2$

$Ca(N{H}_2{)}_2+H_{2}O\to Ca(OH{)}_2+N{H}_3$

$N{H}_3+CaOC{l}_2\to N_2$

$N_2+Mg\to M{g}_3{N}_2$

$M{g}_3{N}_2+H_{2}O\to N{H}_3+Mg(OH{)}_2$
