Silver chloride combines with copper (ii) fluoride to yield silver fluoride and copper (ii) chloride.
agcl (aq) + cuf2 (aq) > agf (s) + cucl2 (aq)
which of the following is the correct set of coefficients to balance this equation above?

2, 1, 2, 1

Silver chloride reacts with Copper (II) fluoride to form Silver fluoride and Copper (II) chloride.

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.
