Explanation

The unbalanced equation: C₃H₈ + O₂ → CO₂ + H₂O

Balancing steps:

  1. Balance carbon: C₃H₈ + O₂ → 3CO₂ + H₂O
  2. Balance hydrogen: C₃H₈ + O₂ → 3CO₂ + 4H₂O
  3. Balance oxygen:
    • Right side has: (3×2) + (4×1) = 10 oxygen atoms
    • Left side needs: 10/2 = 5 O₂ molecules

Balanced equation: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
