Which of the following is a product of combustion?

A product of combustion refers to the substances produced when a fuel undergoes burning in the presence of an oxidizer, usually oxygen. During this chemical reaction, various compounds can be formed depending on the nature of the fuel and the combustion conditions.

Water is a common byproduct of combustion, especially in the case of hydrocarbons, where hydrogen in the fuel combines with oxygen. Carbon monoxide is also produced when there is incomplete combustion, where there isn’t enough oxygen to convert all the carbon in the fuel to carbon dioxide. Finally, while oxygen is typically regarded as a reactant in combustion, it can be present in the exhaust, especially in poorly ventilated or incomplete combustion scenarios.

Thus, considering that both water and carbon monoxide are indeed products of combustion, the correct response encompasses all these elements, affirming that they can all be associated with combustion processes in various forms and conditions. Each plays a role in understanding the dynamics of fire and the chemical transformations occurring when materials burn. This understanding is critical for facility fire brigade members as they respond to fires and manage the potential hazards associated with these combustion byproducts.
