Answer:

4O₂ (g) + 1/2C₅H₁₂ (g) →  5/2CO₂ (g)  +  3H₂O (g)

4 would be the smallest possible integer for O₂

Explanation:

The balanced equation is this one:

8O₂ (g) + C₅H₁₂ (g) →  5CO₂ (g)  +  6H₂O (g)

If we divide stoichiometry /2 (the half) we can consider that we use, the smallest possible integers.

8/2O₂ (g) + 1/2C₅H₁₂ (g) →  5/2CO₂ (g)  +  6/2H₂O (g)

4O₂ (g) + 1/2C₅H₁₂ (g) →  5/2CO₂ (g)  +  3H₂O (g)
