double decomposition reaction is a chemical reaction where two compounds decomposes or breaks to form two new compounds. Equationwise this reaction forms new substances just by the exchange of their radiclas.

A double decomposition reaction is a reaction in which two reactants are both decomposed to from new substances by exchanging their radicals (a radical is a group of atoms of elements which behaves like a single unit and shows one valency).

A double decomposition reaction is the opposite of synthesis. A good example is the electrolysis of water that makes hydrogen gas and oxygen.

Is Zn H2So4 Zn So4 H2 a decomposition reaction?

If you mean Zn + H2SO4 --> ZnSO4 + H2, then no, it is not a decomposition reaction. In decomposition reactions one reactant is broken down into two or more simpler substances. For example, the electrolysis of water, 2H2O --> 2H2 + O2 is a decomposition reaction. The reaction referred to in your question is a double replacement (displacement) reaction. I apologize that the subscripts are not working at this time.
