HEYA FRIEND HERE IS YOUR ANSWER

REDOX REACTION

(A) OXIDATION : addition of oxygen and removal of hydrogen is called oxidation.

(B) REDUCTION : addition of hydrogen and removal of oxygen is called reduction.

1. MnO₂ + 4HCl →  MnCl₂ + 2H₂O + Cl₂

• SUBSTANCE OXIDIZED: HCl
• SUBSTANCE REDUCED:  MnO₂

2. CuO + H₂ →  Cu + H₂O

• SUBSTANCE OXIDIZED: H₂
• SUBSTANCE REDUCED: CuO

HOPE IT HELPS YOU!!!
