Definition: Combustion is a very complex sequence of what are called exothermic chemical reactions between a oxidant and a fuel which are accompanied by the production of heat and most of the time light in the form of flames or a glow. Equation: A + O2 => CO2 + H20

Example: Oxygen and Flourine react with a compound to form the product of the compounds of each element in the fuel with the oxidizing element. CH4 + 2O2 → CO2 + 2H2O

There are six main types of Combustion: 1.Rapid, in which large amounts of heat and light energy are released, usually resulting in fire. 2.Slow, in which the combustion forms at low temperatures. 3.Complete combustion, where the reactant will burn in oxygen, creating a lesser number of products. 4.Turbulent is characterized by turbulent flows. 5.Incomplete, when there is not enough oxygen to allow the fuel to react. 6.Smoldering, when there is a flame-less combustion which gets its heat from a reaction happening on the surface of a solid.

Steps to change the chemical sentence into a formula: 1.Change chemical names to symbols. 2.Figure out charge of each element.

Balancing the equation: 1.Under the equation make a table and count the number of atoms of each element. 2.Change coefficients where needed.

Example: Trichloride Octahydrogen reacts with Dioxide to form Carbon Dioxide and Water. 1.C3H8 + O2 => CO2 + H2O 2.C3H8 + 5O2 => 3CO2 + 4H2O (To balance you need to put a 3 in front of carbon dioxide, a 5 in front of the oxide, and a 4 in front of the hydrogen on the left side.
