AB → A + B



Decomposition or analysis is the separation of a chemical compound into elements or chemical compounds. In order to decompose a compound, it is often necessary to raise the temperature. Decomposition is use in several analytical techniques, notably mass spectrometry, traditional gravimetric analysis & thermogravimetric analysis.



An example of this would be water being broken down into hydrogen gas & oxygen gas. To change it to a formula you write the formula for water which is H2O then an arrow to shows it turns into hydrogen gas which is H2 & oxygen gas which is O2. It would look like this: H2O--->H2 + O2

To balance this equation you first make a chart to show the amount of each elements on both sides: 1 O 2 2 H 2 In order to balance this equation you have to add a 2 to both H2 & H2O this makes the O in the equation to the left have 2 oxygens like the other one & makes both hydrogens have 4 each. 2 O 2 4 H 4 The final equation will be:
