Enter a balanced equation for the reaction of Na2S and CdSO4.

This type of a reaction is a double displacement reaction. where the reactants displace each other. the cations and the anions the reactant compounds replace each other or in other words switch places. the anion of one compound will bond with the cation of the other compound and vice versa.

the equation for the above is

Na₂S + CdSO₄ - - - > CdS + Na₂SO₄

the numbers of atoms on both sides are balanced now
