Answer:
written below-
Explanation:
) The reaction given is: Zn(s)+Cu2^{+} (aq) >Zn^{2+}(aq)+Cu(s)
2) From that, you can see the Zn(s) is loosing the electron since it is being oxidized (from 0 to 2^{+}) while Cu^{2+} isgaining electrons, since it is beingreduced (from 2 to 0)
3) Then, you can already tell thatelectrons go from Zn to Cu
4) The plate where oxidation occurs iscalled anode, and the plate wherereduction occus is called cathode`
So you get that the electrons flowfrom the anode (Zn) to the cathode(Cu).Always oxidation occurs at theanode, and reduction occurs at the cathode.
