Question

Octane,C8H18,is a major component in gasoline.What is the coefficient of oxygen in the balanced equation for the combustion of octane? __C8H18(g)+ __O₂(g)  __CO₂(g)+ __H₂O(g)

Quizplus · Accepted Answer

The balanced equation for the combustion of octane is:
C8H18(g) + 12.5O2(g) → 8CO2(g) + 9H2O(g)
Therefore, the coefficient of oxygen is 12.5, which can be simplified to 25 when all coefficients are multiplied by 2.5. Therefore, the correct choice is B.
