(B) hydrogen sulphide gas burns in air to give water and sulphur dioxide
(C) barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate
(D) potassium metal reacts with water to give potassium hydroxide and hydrogen gas

Answer 1

(a) 3H2 (g) + N2 (g) → 2NH3 (g)

(b) 2H2S (g) + 3O2 (g) → 2H2O (l) + 2SO2 (g)

(c) 3BaCl2 (aq) + Al2(SO4)3 (aq) → 2AlCl3 (aq) + 3BaSO4 (s)

(d) 2K (s) + 2H2O (l) → 2KOH (aq) + H2(g)
