Combustion+Brock

__**Combustion**__
Combustion is when a hydrocarbon reacts with oxygen to form carbon dioxide and water. The equation is set up like this: A + O2 => H2O + CO2

An example of a combustion reaction is: trichloride octahydrogen reacts with dioxide to form carbon dioxide and water. To turn this sentence into an equation you just do what it tells you, so it looks like this: C3H8 + O2 => CO2 + H2O

The problem with this equation is it's not balanced. To balance it we put a 3 in front of the carbon dioxide, so that the carbon is balanced on the left side. Then we put a 5 in front of the dioxide to balance the oxygen on the right side. Finally we put a 4 in front of the hydrogen on the left side.

So the balanced equation looks like this: C3H8 + 5O2 => 3CO2 + 4H2O

To be positive we balanced it correctly we just do the chart:

__3__ C __3__ __8__ H __8__ __10__ O __10
