What occurs during a combustion reaction?

During a combustion reaction, a substance typically reacts with oxygen in the presence of heat, resulting in the release of energy in the form of heat and light. This process often involves the burning of fuels, such as hydrocarbons, where the products are usually carbon dioxide and water. The key aspect of combustion is the rapid oxidation that occurs, which is characterized by a noticeable release of energy that can produce flame and heat.

This understanding is crucial in various applications, such as in internal combustion engines, heating systems, and even fireworks. The reaction can be complete, producing carbon dioxide and water, or incomplete, leading to the formation of carbon monoxide or soot if there isn’t enough oxygen available. The focus is on the interaction with oxygen and the energy produced, which helps differentiate combustion reactions from other chemical interactions, such as combining with a base or changing color.
