Combustion:

Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant , usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. In simple words, combustion is the process of burning a fuel in the presence of oxygen to release heat energy . This process is commonly used in cars, airplanes, power plants, industrial furnaces, and household cooking or heating devices. This page provides an overview of combustion reactions, emphasizing their need for oxygen and energy release. It discusses examples like roasting marshmallows and the combustion of hydrocarbons, … What is a Combustion Reaction? A combustion reaction is a reaction of a substance with oxygen gas to release relatively large amounts of energy . Because combustion reactions are often characterized by the presence of flames, a substance undergoing combustion is often said to be burning.
