Question

(A) is a colourless solid, it metal when heated and gives of a gas (B) Which is supporter of combustion , if heating is contimed the white of the solid disuppears , When (A) is heatyed with an aqueous `NaOH` solution , an alkaline gas (C ) is evolved ,When gas(B) is leasted with sodumine ,a colourless solid (D) is formed .When (D) is heated with dil `H_(2)SO_(4)` a colourless liquid (F) is formed .
The mass of compound E is
A. Ammonia
B. Hydrazoic acid
C. Hydrogen amide
D. None of these

Answer 1

Correct Answer - b
(A)is `NH_(4)NO_(3)` reactions are
i. `underset((A))(NH_(4)NO_(3) underset((B))(N_(2) O) + 2H_(2)O`
ii `NH_(4)NO_(3) + NaOH overset(Heat)rarr underset((C))(NH_(3)uarr) +NaNO_(3)+H_(2)O`
iii. `underset((B))(N_(2)O)+NaNH_(2) rarr underset("Sodium azide"(D))(NaN_(3))+H_(2)O`
`NaN_(3) +H_(2)SO_(4) + underset((E)"hydrazoic acid")(HN_(3))+NaHSO_(4)`
`Pb(N_(3))_(2), AgN_(3)` (azides) are expolsive.
