What is the product of the complete combustion of propane?

The complete combustion of propane, a hydrocarbon with the chemical formula C3H8, involves a reaction with oxygen, resulting in the formation of carbon dioxide and water as the primary products.

During complete combustion, propane is oxidized fully in an ample supply of oxygen, producing carbon dioxide (CO2) and water (H2O). This is a typical reaction for alkanes, where the complete oxidation of the molecules leads to the release of energy, typically observed as heat and light.

In the case of propane, the balanced chemical equation for its complete combustion is:

C3H8 + 5O2 → 3CO2 + 4H2O

This equation clearly shows that for every mole of propane combusted, three moles of carbon dioxide and four moles of water are produced. Hence, the correct answer highlights the products of this complete combustion process, emphasizing the transformation of a hydrocarbon and its combustion reactions under sufficient oxygen supply.
