### Test 2 Question 8 wording

In question 8 it says that the following half-reactions are unbalanced, but their charges and the moles of each atom are equal on either side, so how are they unbalanced?

The electrons in each half-reaction have to be equal before you can create the overall balanced reaction.

Hi, I believe that Test 2 question 8 is different for different discussion sections. Would you be able to send the problem?

The two half reactions given are:

Ag + I- ----> AgI + e- (anode) = -0.15 V
AgCl +e- ---> Ag + Cl- (cathode) = +0.22 V
