Reaction+Five+Combustion


 * __Combustion Reactions__**

--> When a substance combines with oxygen, releasing a large amount of energy in the form of light and heat.

__Sentence Form of Reaction:__

Hydrocarbons react with Oxygen Gas to form Water and Carbon Dioxide.

__Conversion to Reaction:__ >This is a differnt reaction in the sense that, these are no longer Ionic Bonds, but Covalent. So we use the names that they are given in the sentence form to help us come up with the correct symbols and subscripts in the reactions formula.

CH4 + O2 --> H2O + CO2

__Balancing the Equation:__

The process for balancing the equation does not change, you still are looking for the coefficients that will help to bring eqaulity to each side of the reaction. So first you see that there is 3 O atoms on the right side of the reaction, To make things easier you can add the coefficient 2 in front of H2O to make the right side of the equation have 4 atoms of O. After doing that you will need to add the coefficient 2 in front of O2 on the left side. CH4 + 2 O2 --> 2 H2O + CO2 The rest of the equation is already equal so those are the only coefficients that you need to put into the formula, leaving you with


 * CH4 + 2 O2 --> 2 H2O + CO2** > The final formula for this Combustion Reaction.
