Chemical reaction: HCl + Ba → BaCl₂ + H₂.

Oxidation reaction: Ba⁰ → Ba⁺² + 2e⁻.

Reduction reaction: 2H⁺ + 2e⁻ → H₂⁰.

Balanced chemical reaction: 2HCl + Ba→ BaCl₂ + H₂.

Barium (Ba) change oxidation number from 0 to +2 (lose electrons), barium is oxidized (reducing agent).

Hydrogen change oxidation number from +1 to 0 (gain electrons), it is reduced.
