The gas commonly produced during combustion reactions is carbon dioxide (CO2). Combustion is a chemical process in which a fuel reacts with oxygen, releasing energy in the form of heat and light. While carbon dioxide is a primary product, combustion reactions can also produce other gases, such as carbon monoxide (CO) and nitrogen oxides (NOx), depending on the conditions and materials involved. The emission of carbon dioxide is significant because it contributes to climate change when released in large quantities from industrial processes and vehicles. Managing combustion emissions is crucial for environmental sustainability.
