प्रश्न
A substance 'A' was heated with slaked lime and a gas 'B' with the pungent smell was obtained. Name the substances A and B and give a balanced equation.
उत्तर
The substance A is Ammonium chloride \[\ce{(NH4Cl)}\] and 'B' is Ammonia \[\ce{(NH3)}\].
\[\ce{\underset{Ammonium chloride}{2NH4Cl} + \underset{slaked lime}{Ca(OH)2} ->[\Delta] CaCl2_{(s)} + 2H2O + 2NH3}\]
