Combustion ( /kəmˈbʌs.tʃən/) or burning is the sequence of 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 oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element. For example:
A simple example can be seen in the combustion of hydrogen and oxygen, which is a commonly used reaction in rocket engines:
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 carbon monoxide and pure carbon (soot or ash). Additionally, any combustion in atmospheric air, which is 78% nitrogen, will also create several forms of nitrogen oxides.
[sample1]:
Gentlemen, may I have your attention please?
[sample2]:
There's stuff coming back at you all the time!
[sample3]:
You have to do it and do it together, do it and do it together

Burning, burning
Destiny comes knocking on your door
Takes you were the money meets the floor
Jealousy comes creeping up on you
And make you do those things that you hate to do
[chorus 1]:
Yes I'm burning
She won't get away
(Burning) 'cause I'm here to say
She's coming back
And it's a fact
She's here to stay
Everybody wants a piece of you
And charity begins at the age of two
So baby, baby, baby, shut your door
'Cause I won't leave you on this killing floor
[chorus 2]:
'Cause I'm burning
She won't get away
(Burning) 'cause I'm here to say
She's coming back
And it's a fact
She's here to stay
[sample 4]
Hello. Yes, you're on the air
[sample 5]
Hello?

Burning, Burning
