translating word equations into balanced chemical equations
CO₂ + 4 H₂O Oxygen: 2 (from O₂) on reactant side, on the right: 3×2 + 4×1 = 6 + 4 = 10 oxygen atoms. To balance oxygen, put 5 in front of O₂ (since 5×2=10): C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O Final balanced equation: C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O Example 2: Aci
