As we learnt

 

Decomposition Reaction -

 

This is opposite of combination reaction precisely, a decomposition reaction lead to the breakdown of a compound into two or more components at least one of which must be in an elemental state.

- wherein

2H_{2}O(l)\overset{\Delta}{\rightarrow}2H_{2}(g)+O_{2}(g)

+1     -2                 0               0

 

 

HgO\rightarrow Hg+\frac{1}{2}O_2 is a decomposition reaction since a compound is breaking down into two or more components atleast one of which is in elemental state.
