AgCl (aq) + CuF2 (aq) ----> AgF (s) + CuCl2 (aq)
The balanced chemical equation will be;
2AgCl (aq) + CuF2 (aq) ----> 2AgF (s) + CuCl2 (aq)
Balancing a chemical equation ensures that the Law of conservation of mass is conserved , such that the number of atoms of each element on either side of the equation is equal.
