(i) AlN + 3H2O ⟶ Al(OH)3 + NH3 [g]
(ii) Cu + 4HNO3 ⟶ Cu(NO3)2 + 2H2O + 2NO2
(iii) NaHCO3 + HCl ⟶ NaCl + H2O + CO2 ↑
(iv) Na2SO3 + H2SO4 (dil) ⟶ Na2SO4 + H2O + SO2
(v) $\underset{\text{ Chloroethane [ethyl chloride]}}{\text{C}_2\text{H}_5\text{-Cl}} + \text{NaOH [aq.]} \xrightarrow{\text{boil}} \underset{\text{ Ethanol [ethyl alcohol]}}{\text{C}_2\text{H}_5\text{-OH}} + \text{NaCl}$
