Consider the half reactions below for a chemical reaction. Upper Z n right arrow upper Z n superscript 2 plus (a q) plus 2 e superscript minus. Second line: upper C u superscript 2 plus (a q)plus 2 e superscript minus right arrow upper C u (s).

What is the overall equation for this chemical reaction?
Upper Z n (s) plus upper C u superscript 2 plus (a q) right arrow upper Z n superscript 2 plus (a q) plus upper C u (s).
Upper Z n (s) plus upper C u superscript 2 plus (a q) right arrow upper C u superscript 2 plus (a q) plus upper Z n (s).
Upper Z n superscript 2 plus (a q) plus upper C u (s) right arrow upper C u superscript 2 plus (a q) plus upper Z n (s).
Upper Z n superscript 2 plus (a q) plus 2 e superscript minus right arrow upper C u superscript 2 plus (a q) plus 2 e superscript plus.
