What are the products of the complete combustion of a hydrocarbon?

The complete combustion of a hydrocarbon results in the formation of carbon dioxide and water. In this process, the hydrocarbon reacts with oxygen, resulting in the molecules breaking down to release energy, producing carbon dioxide (CO₂) as a byproduct, along with water (H₂O).

During complete combustion, there is an ample supply of oxygen, ensuring that the carbon in the hydrocarbon is fully oxidized to carbon dioxide instead of forming carbon monoxide or soot, which can occur in conditions of incomplete combustion. This thorough oxidation is essential for maximizing energy release and minimizing harmful emissions.

In summary, when a hydrocarbon undergoes complete combustion, it will always produce carbon dioxide and water, making that the defining answer to the question regarding the products of this chemical reaction.
