What two general products do combustion reactions create?

Reaction of combustion, always generate CO₂ and H₂O, with O₂ as a reactant.

Explanation:

The combustion reaction is a type of exothermic chemical reaction, where carbon dioxide and water are generated, as products. It is an exothermic reaction where heat is released and a flame is formed. When combustible substances react to the maximum possible degree of oxidation, we speak of complete combustion.

This is the combustion for methane:

CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (g)

This is the combustion for propanol

2C₃H₇OH (l) + 9O₂ (g) → 6CO₂ (g) + 8H₂O (g)

This is the combustion for acetic acid

CH₃COOH (l) + 2O₂ (g) → 2CO₂ (g) + 2H₂O (g)
