उत्तर
Action of heat on ammonium chloride is reversible. When heated, it decomposes to form ammonia and hydrogen chloride. When the products are cooled, they recombine to form ammonium chloride .
\[\ce{NH4CI <=> NH3 + HCI}\]
Ammonium nitrate on heating completely disappears, escaping in the form of water vapour and nitrous oxide.
\[\ce{NH4NO3 ->[\Delta] N2O + 2H2O}\]
