Solution

(A) is ${N H}_{4} {N O}_{2}$ . It reacts with NaOH to form the gas (B) which is ${N H}_{3}$ and the solution (C) which is ${N a N O}_{2}$
${N H}_{4} {N O}_{2} + N a O H \to N H_{3} ↑ + N a N O_{2} + H_{2} O$
Ammonia reacts with HCl to form white fumes of ammonium chloride.
$N H_{3} + H C l \to N H_{4} C l$
Ammonium nitrite on heating produces water along with gas (D) which is $N_{2}$
$N H_{4} N O_{2} h e a t - - \to H_{2} O + N_{2} ↑$
Nitrogen on heating with aluminum forms aluminum nitride which is E..
$N_{2} + A l h e a t - - \to A l N$
Aluminum nitride on hydrolysis with water forms aluminum hydroxide and ammonia (B).
$A l N + 3 H_{2} O \to A l (O H)_{3} + N H_{3}$
When sodium nitrite is treated with zinc in slightly alkaline medium, ammonia gas (B) is evolved.
$Z n + 2 N a O H \to N a_{2} Z n O_{2} + 2 H$
$N a N O_{2} + 6 H \to N a O H + H_{2} O + N H_{3} ↑$
