Fuel + Oxygen ---> carbon dioxide + water
Burning is called combustion.
What Happens During A Combustion Reaction?
The most common combustion reaction occurs when a carbon compound reacts with oxygen to produce carbon dioxide and water. This is called pure or complete combustion. When you have incomplete combustion, other products form such as carbon (soot) or carbon monoxide.
