Decomposition Reaction ( Analysis Reaction )

                          In decomposition reaction a compound is broken into elements or simpler compounds. It is also known analysis reaction.

General Reaction:
            AB       ----->   A     +      B

Example :
Split into two elements.
2H2O    →   2H2    +   O2
MgCl2    →  Mg    +   Cl2
2KCl    →     2K    +     Cl2
FeS       →  Fe    +    S

2KClO3    →   2KCl     +    3O2

Split into two simpler compounds.
CaCO3  →  CaO  +  CO2
H2CO3  →  H2O  +  CO2

Na2CO3  →  Na2O  +  CO2
