MCQ
An inorganic salt $(A)$ is decomposed on heating to give two products $(B)$ and $(C)$. Compound $(C)$ is a liquid at room temperature and is neutral to litmus while the compound $(B)$ is a colourless neutral gas. Compounds $(A)$, $(B)$ and $(C)$ are
  • ✓
    $NH_4NO_3,\,N_2O,\,H_2O$
  • B
    $NH_4NO_2,\,NO,\,H_2O$
  • C
    $CaO,\,H_2O,\,CaCl_2$
  • D
    $Ba(NO_3)_2,\,H_2O,\,NO_2$
✓

Answer

Correct option: A.
$NH_4NO_3,\,N_2O,\,H_2O$
a
Reaction involved is :

$\mathop {N{H_4}N{O_3}\,}\limits_A \xrightarrow{\Delta }\,\mathop {{N_2}O}\limits_B \, + \,\mathop {2{H_2}O}\limits_C $

Hence option $(a)$ is correct.
