Post 1 Chemical Reactions

We just started a new unit beginning with the CHO method and combustion of balancing equations.
Combustion: 1. will always react with oxygen,
                     2. is an exothermic reaction
                     3. always produces CO2 and H2O
We began are unit with just balancing equations. If the prefix is represented in a decimal, the whole equation should be multiplied to equal whole numbers. Also, don't forget that, opposed to the common nomenclature rules, methane is CH4 and ammonia is NH3.
Here's a good video to start the unit off. khanacademy
