Decomposition is a reaction in which a single substance is broken down into two or more simpler substances. This can be represented by AB > A+B

An example of decomposition would be sodium chloride. In order to write this you have to write the symbol for the element. Then figure out the charge of each element ( to find this you need to know what group number it is in in the periodic table of elements). Then you take the charge of the element and do the switchero. Then if you can reduce. The formula for this is: NaCl---> Na+Cl2

The balanced equation would be: 2NaCl> 2Na+Cl2 To balance this equation you would have to make sure there are the same number of atoms of each element on both sides. In order to do that you must put a coefficient of 2 in front of the NaCl and on the product side before the Na.
