Question

An inorganic salt $\left(A\right)$ is decomposed on heating to give two products $\left(B\right)$ and $\left(C\right)$. Compound $\left(C\right)$ is a liquid a room temperature and is neutral to litmus while the compound $\left(B\right)$ is a colourless neutral gas. Compounds $\left(A\right),\left(B\right)$ and $\left(C\right)$ are

• A. $N{H}_{4}N{O}_3,N_{2}O,H_{2}O$
• B. $N{H}_{4}N{O}_2,NO,H_{2}O$
• C. $CaO,H_{2}O,CaC{l}_2$
• D. $Ba(N{O}_3{)}_2,H_{2}O,N{O}_2$
• E. $Mg(N{O}_3{)}_2,N_2{O}_5,H_{2}O$

Answer 1

Answer: (A)

$N{H}_{4}N{O}_3,N_{2}O,H_{2}O$

$\underset{A}{N{H}_{4}N{O}_3\left(s\right)}\to \underset{B}{N_{2}O\left(g\right)}+\underset{C}{2H_{2}O\left(l\right)}$.
