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"] .

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
