Consider the half reactions below for a chemical reaction. Zn——>Zn2+ (aq) + 2e-
Cu2+ (aq) + 2e- ——> Cu(s)
What is the overall equation for this chemical reaction?
Zn(s)+ Cu2+ (aq)
Zn2+ (aq) + Cu(s)
Zn(s) + Cu2+ (aq) Cu2+ (aq) + 2e-
Zn2+ (aq) + Cu(s)-> Cu2+ (aq) + Zn(s)
Zn2+ (aq) + 2e--> Cu2+ (aq) + 2e-
