Combustion is a chemical process which involves the burning or rapid oxidation of a fuel.
Complete combustion reaction means when a hydrocarbon reacts with sufficient amount of oxygen forming carbon dioxide and water.
Incomplete combustion reaction means when a hydrocarbon reacts with insufficient amount of oxygen forming carbon monoxide and water.
Incomplete combustion cause environmental pollution.
Complete combustion results in more energy than incomplete combustion.
Combustion is the process of burning or oxidation, which may be accompanied by light and heat. Oxygen itself does not burn, but it supports combustion. The rate of combustion is influenced by both oxygen concentration and its partial pressure.
