Answer:

((a) 3H2 + N2 → 2NH3

The following chemical reaction takes place when hydrogen gas interacts with nitrogen to form ammonia. Hydrogen and nitrogen react together to form ammonia in this scenario.

H2 + N2 → NH3

Balancing the above equation, we get

3H2 + N2 → 2NH3

(b) 2H2S + 3O2 → 2H2O + 2SO2

Hydrogen sulphide gas burns in air to give water and sulphur dioxide can be expressed in terms of equation as

H2S + O2 → H2O + SO2 (unbalanced equation)

The balanced equation is

2H2S + 3O2 → 2H2O + 2SO2

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

Barium chloride on reacting with ammonium sulphate forms barium sulphate and ammonium chloride. The reaction is an example of a double displacement reaction since ammonium and barium are getting displaced from their respective salts. The chemical equation can be represented as

Aluminium sulfate + Barium chloride → Aluminum chloride + Barium sulfate

Al2(SO4)3 + 3BaCl2→ 2AlCl3 + 3BaSO4

(d) 2K + 2H2O → 2KOH + H2

Potassium hydroxide and hydrogen gas are formed when potassium metal reacts with water.

K + H2O → KOH + H2 (unbalanced equation)

The balanced equation is

2K + 2H2O → 2KOH + H2
