Which equation correctly represents the balanced equation for the complete combustion of a hydrocarbon with the formula CₓHᵧ?
ACₓHᵧ + (x + y/2)O₂ → xCO₂ + y/2 H₂O
BCₓHᵧ + (x + y/4)O₂ → xCO₂ + y/2 H₂O
CCₓHᵧ + (x + y/2)O₂ → xCO₂ + y/4 H₂O
DCₓHᵧ + (x + y/4)O₂ → xCO₂ + y/4 H₂O
✓ Correct answer
D: CₓHᵧ + (x + y/4)O₂ → xCO₂ + y/4 H₂O
