Decomposition reaction is called opposite of combination reaction because -----------------
In a combination reaction , two or more reactants combine to give a single product .
Ex CaO + H2O --------- Ca( OH )2
In a decomposition reaction , a single reactant breaks down into two or more simpler products .
Ex CaCO3------------ CaO + CO2 .
So they are opposite to each other .
