Final answer:
The balanced chemical equation for the combustion of C₇H₈O is C₇H₈O + 9O₂ → 7CO₂ + 4H₂O.
Step-by-step explanation:
A balanced chemical equation for the combustion of C₇H₈O with oxygen gas to produce gaseous carbon dioxide and water vapor is:
C₇H₈O (l) + 9O₂ (g) → 7CO₂ (g) + 4H₂O (g)
In this equation, C₇H₈O is the liquid fuel being burned, O₂ is the oxygen gas, CO₂ is the gaseous carbon dioxide, and H₂O is the water vapor.
