What are the products of a complete combustion reaction?

In a complete combustion reaction, a hydrocarbon reacts with oxygen to produce carbon dioxide and water as the primary products. This reaction releases energy in the form of heat and light, which is why it is often utilized in engines and heating systems. The combustion process typically involves the complete oxidation of the hydrocarbon, ensuring that enough oxygen is present for all the carbon atoms in the compound to convert to carbon dioxide and all the hydrogen atoms to convert to water.

The correct choice reflects this well-established outcome of the reaction, emphasizing that both carbon dioxide and water are generated when hydrocarbons undergo complete combustion in the presence of sufficient oxygen. Understanding this principle is crucial for various applications in chemistry and environmental science, as it relates to energy production and emissions from combustion processes.
