Consider the following general voltaic cell and a cell notation, and answer all three parts of this question.

mg(s) | mg2+(aq) || cl2(g) | cl−(aq) | c(s)

part 1: based on the cell notation, the substance of electrode a is [ select ] ["mg(s)", "c(s)", ""] , and the substance of electrode b is [ select ] ["c(s)", "mg(s)"] .

part 2: what is the balanced redox equation for the voltaic cell?

a) mg2+(aq) + 2 cl−(aq) \rightarrow → mg(s) + cl2(g)

b) mg2+(aq) + cl−(aq) \rightarrow → mg(s) + cl2(g)

c) mg(s) + cl2(g) \rightarrow → mg2+(aq) + 2 cl−(aq)

d) mg(s) + cl2(g) \rightarrow → mg2+(aq) + cl−(aq)

e) none of the above is correct, because c(s) doesn't appear in any of them.

part 3:

- if the salt bridge contains nano3, na+ ions flow to the [ select ] ["left", "right"] , and no3− ions flow to the [ select ] ["left", "right"] .

- electrons flow from electrode [ select ] ["a", "b"] to electrode [ select ] ["b", "a"] .
