Beanie · Answer 1

1 mol of octane produced 8 mol of carbon dioxide when it reacts with oxygen gas.

Explanation:

The combustion reaction of octane is represented in the reaction bellow:

C₈H₁₈ (l) + 17,5O₂ (g) → 8CO₂ (g) + 9H₂O (g)

The balanced equation shows that 1 mol of C₈H₁₈ generates 8 mol of CO₂ in the presence of, at least, 17,5 mol of O₂.
