(ii) Action of hot and concentrated Nitric acid on copper.

(iii) Action of Hydrochloric acid on sodium bicarbonate.

(iv) Action of dilute Sulphuric acid on Sodium Sulphite.

(v) Preparation of ethanol from Ethyl Chloride.

Answer

(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) C2H5-Cl Chloroethane [ethyl chloride]+NaOH [aq.]→boilC2H5-OH Ethanol [ethyl alcohol]+NaCl\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}
