Question

A major component of gasoline is octane . When liquid octane is burned in air it reacts with oxygen gas to produce carbon dioxide gas and water vapor. Calculate the moles of carbon dioxide produced by the reaction of of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer 1

Answer:

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.

Answer 2

Answer:

0.768
