Sagot :
Cd + 2HCl → CdCl₂ + H₂, 2ZnS + 3O₂ → 2ZnO + 2SO₂ and CH₄ + 2O₂ → CO₂ + 2H₂O reactions are redox reaction.
What is redox reaction?
Redox reactions are those reactions in which oxidation and reduction process takes place simultaneously.
- Cd + 2HCl → CdCl₂ + H₂
Above balanced equation is a redox reaction as in this reaction oxidation of Cadmium takes place from 0 to+2 state and reduction of hydrogen takes place from +1 to 0 state.
- CuCl₂ + Na₂S → 2NaCl + CuS
- CaCO₃ → CaO + CO₂
Above two balanced reaction are not the redox reaction as their is no oxidation or reduction takes place.
- 2ZnS + 3O₂ → 2ZnO + 2SO₂
Above balanced equation is a redox reaction as in this reaction oxidation of sulfur takes place from -2 to+4 state and reduction of oxygen takes place from 0 to -2 state.
- CH₄ + 2O₂ → CO₂ + 2H₂O
Above balanced equation is a redox reaction as in this reaction oxidation of carbon takes place from -4 to+4 state and reduction of oxygen takes place from 0 to -2 state.
Hence, Cd + 2HCl → CdCl₂ + H₂, 2ZnS + 3O₂ → 2ZnO + 2SO₂ and CH₄ + 2O₂ → CO₂ + 2H₂O reactions are redox reaction
