The correct option is A True
A = NH4NO2.
It reacts with NaOH to form the gas(B) NH3 and the solution (C) NaNO2
NH4NO2+NaOH→NH3↑+NaNO2+H2O
Ammonia reacts with HCl to form white fumes of ammonium chloride.
NH3+HCl→NH4Cl
Ammonium nitrite on heating produces water along with gas (D) N2
NH4NO2heat−−→H2O+N2↑.
Nitrogne on heating with aluminum forms aluminum nitride E.
N2+Alheat−−→AlN
Aluminum nitride on hydrolysis with water forms aluminum hydroxide and ammonia (B).
AlN+3H2O→Al(OH)3+NH3
