old question

Balance each of the following redox reactions occurring in acidic aqueous solution.

1) Zn(s)+Sn2+(aq) ? Zn2+(aq)+Sn(s)

Express your answer as a chemical equation. Identify all of the phases in your answer.

2)Zn(s)+Na+(aq) ? Zn2+(aq)+Na(s)

Express your answer as a chemical equation. Identify all of the phases in your answer.

Zn(s)+Sn2+(aq)?Zn2+(aq)+Sn(s)

Balance each half-reaction.

Zn(s) ==> Zn2+(aq) . .add 2e- to the right side to balance the charge.

Zn(s) ==> Zn2+(aq) + 2e-

Na+(aq) ==> Na(s) . .add 1 e- to the left side to balance the charge.

Na+(aq) + e- ==> Na(s) . . .multiply this equation by 2 so it will match the 2e- in the Zn reaction. Then add the two together (the e's cancel).

2Na+(aq) + 2e- ==> 2Na(s)
Zn(s) ==> Zn2+(aq) + 2e-
==================
2Na+(aq) + Zn(s) ==> 2Na(s) + Zn2+(aq)
