Answer
(a) AlN + 3H2O ⟶ Al(OH)3 + NH3↑
(b) 2NH3 + 3PbO ⟶ 3Pb + 3H2O + N2 [g]
(c) NH3 + 3Cl2 [excess] ⟶ 3HCl + NCl3
(d) 2NH3 + CO2 ⟶ NH2CONH2 + H2O
(i) Ammonia acts as a reducing agent as it loses hydrogen in equation (c).
(ii) Urea is prepared from equation (d). Ammonia reacts with carbon dioxide at 150°C and 150 atm, pressure to give urea.
