Double displacement reaction

thanks

hope this will help you

Answer 2

This is an example of double displacement reaction or double decomposition reaction,since there is exchange of radicals.

On the left hand side ,we can see Ca2+ radical combines with  Cl2- radical and H+ radical combines with SO42- radical.

On the right hand side ,we can see Ca2+ radical combines with  SO42- radical and H+ radical combines with Cl- radical.
