From the list Cs, Mg (ON3) 2, Zn, Ag. Select the substance to be used to displace copper

From the list Cs, Mg (ON3) 2, Zn, Ag. Select the substance to be used to displace copper from the copper sulfate solution (2). Write a reaction equation in molecular form.

As a result of the reaction that takes place between the solution of bivalent copper sulfate and the active metal zinc, which we will choose from the list of chemicals presented in the task. Since zinc is one of the most active metals, it will easily displace copper from the salt. As a result of the passage of a chemical reaction, we get zinc sulfate salt and pure copper. This reaction proceeds according to the type of exchange. The molecular equation of the reaction can be written as follows:
CuSO4 + Zn = Cu ↓ + ZnSO4.
