Given the balanced ionic equation:

Zn (s) + Cu2 + (aq) → Zn2 + (aq) + Cu (s)

Which equation represents the oxidation half reaction?

(1) Zn (s) + 2e - → Zn2 + (aq)

(2) Zn (s) → Zn2 + (aq) + 2e-

(3) Cu2 + (aq) → Cu (s) + 2e-

(4) Cu2 + (aq) + 2e - → Cu (s)

Since they asked oxidation half equation, the answer should be (2).

Given the balanced ionic equation:Zn (s) + Cu2 + (aq) → Zn2 + (aq) + Cu (s)Which equation represents the oxidation half reaction?(1) Zn (s) + 2e - → Zn2 + (aq)(2) Zn (s) → Zn2 + (aq) + 2e-(3) Cu2 + (aq) → Cu (s) + 2e-(4) Cu2 + (aq) + 2e - → Cu (s)
