Answer to Question #101704 in General Chemistry for kvkuv

Question

Predict the products of the following reactions. Write balanced equations including states. C8H18 undergoes complete combustion.

Answer 1

The reaction of complete combustion of octane:

2C₈H₁₈ (liquid) + 25O₂ (gas) = ​​16CO₂ (gas) + 18H₂O (liquid)

With complete combustion (when oxygen is enough), alkanes form carbon dioxide and water. If there is a little oxygen, carbon monoxide is formed instead of carbon dioxide, if not enough, then soot.
