When octane (C₈H₁₈, density = 0.699 g/mL) undergoes complete combustion, it provides energy according to the reaction:
2C₈H₁₈ (l) + 25O₂(g) → 16CO₂(g) + 18H₂O(l). ΔH° = -10,392 kJ
How much heat, in kJ, is produced by the amount of octane needed to drive 829 kilometers in a car that averages 20 km/L?
