*Date: [http://www.wikipedia.org/wiki/15th_Century 15th century]
==Definitions==
*1 : an [[act]] or instance of burning
*2 : a usually rapid [[chemical]] [[process]] (as oxidation) that produces [[heat]] and usually [[light]]; also : a slower oxidation (as in the [[body]])
*3 : [[violent]] agitation : tumult
==Description==
'''Combustion''' or burning is the [[sequence]] of [http://en.wikipedia.org/wiki/Exothermic exothermic] [[chemical]] [[reactions]] between a fuel and an oxidant accompanied by the production of [[heat]] and [[conversion]] of [[chemical]] [[species]]. The release of [[heat]] can result in the production of [[light]] in the form of either [[glowing]] or a [[flame]]. Fuels of interest often include organic compounds (especially hydrocarbons) in the [[gas]], [[liquid]] or [[solid]] [[phase]].
In a complete combustion [[reaction]], a compound reacts with an oxidizing [[element]], such as [http://en.wikipedia.org/wiki/Oxygen oxygen] or [http://en.wikipedia.org/wiki/Fluorine fluorine], and the products are compounds of each [[element]] in the fuel with the oxidizing element. For example:
:CH4 + 2O2 → CO2 + 2H2O + [[energy]]
:CH2S + 6F2 → CF4 + 2HF + SF6
A simple example can be seen in the combustion of [http://en.wikipedia.org/wiki/Hydrogen hydrogen] and [http://en.wikipedia.org/wiki/Oxygen oxygen], which is a commonly used [[reaction]] in [http://en.wikipedia.org/wiki/Rocket_engines rocket engines]:
:2H2 + O2 → 2H2O(g) + [[heat]]
The result is [[water]] vapor.
Complete combustion is almost impossible to [[achieve]]. In [[reality]], as [[actual]] combustion [[reactions]] come to [[equilibrium]], a wide variety of major and minor species will be present such as [http://en.wikipedia.org/wiki/Carbon_monoxide carbon monoxide] and pure [http://en.wikipedia.org/wiki/Carbon carbon] (soot or ash). Additionally, any combustion in [[air]], which is 78% [http://en.wikipedia.org/wiki/Nitrogen nitrogen], will also create several forms of [http://en.wikipedia.org/wiki/Nitrogen_oxides nitrogen oxides].[http://en.wikipedia.org/wiki/Combustion]
