Test 2 Question 6 Part D

[Gwen Peng 1L]

For this question wouldn't you just use the formula: E(cell)=E(cathode)-E(anode), which means it would be +2.07 V- (-1.24 V)= +3.31 V?

[Anna Goldberg 2I]

Yes, that is the formula that you use.
I would have to know the values for E cathode and E anode in order to tell you if your E cell is correct.

[Beza Ayalew 1I]

if you used the standard potentials from the equations given on the back of test and didn't flip the signs, and didn't confuse the cathode vs the anode, your work is fine so your answer should be right
