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)

Answer 2

A) Hydrogen gas combines with Nitrogen to form Ammonia.

A) 3H2 (g) + N2 (g) → 2NH3 (g)

=========================================

B) Hydrogen Sulphide gas Burns in air to give water and sulphur dioxide

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

=========================================

C) Aqueous solution of Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate.

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

=========================================

D) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.

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

=========================================

E) Methane gas Burns in oxygen of air to give carbon dioxide and water.

E) CH4 + 2 O2 → CO2 + 2 H2O

=========================================

F) Calcium oxide combines vigorously in water to give Calcium Hydroxide.

F) CaO + H2O → Ca(OH)2 + heat

=========================================
