Consider the half reactions below for a chemical reaction.
2 Equations: First: upper M g right arrow upper M g superscript 2 plus (a q) plus 2 e superscript minus. Second: 2 upper H superscript plus (a q) plus 2 superscript plus right arrow upper H subscript 2 (g).
What is the overall equation for this chemical reaction?
Upper M g (s) plus 2 upper H superscript plus (a q) right arrow upper M g superscript 2 plus (a q) plus upper H subscript 2 (g).
Upper M g (s) plus 2 upper H superscript plus (a q) right arrow upper M g superscript 2 plus (a q) plus 2 e superscript minus.
Upper M g superscript 2 plus (a q) plus upper H subscript 2 (g) right arrow upper M g (s) plus 2 upper H superscript plus (a q).
Upper M g (s) plus 2 upper H right arrow upper M g (a q) plus upper H subscript 2 (g).
