MCQ
Nitrogen is obtained when $NaN{O_2}$ reacts with
  • ✓
    $N{H_4}Cl$
  • B
    $N{H_4}N{O_3}$
  • C
    ${(N{H_4})_2}C{O_3}$
  • D
    $N{H_4}OH$
✓

Answer

Correct option: A.
$N{H_4}Cl$
a
(a)$N{H_4}Cl + NaN{O_2} \overset {\Delta} \longrightarrow N{H_4}N{O_2}$

$N{H_4}N{O_2} \longrightarrow {N_2} + 2{H_2}O$
