A cell can be prepared from copper and tin. What is the E° cell for the cell that forms from the following half reactions?

A cell can be prepared from copper and tin. What is the E° cell for the cell that forms from the following half reactions?

Cu2+(aq) + 2e-Cu(s) E° = 0.35 V
Sn4+(aq) + 2e- Sn2+(aq) E° = 0.13 V

Choose the correct options:

a. 0.48 V
b. 0.22 V
c. -0.48 V
d. -0.22 V

Correct answer is option A. 0.48 V. Explanation: A cell can be prepared from copper and tin. 0.48 V is the E° cellfor the cell that forms from the following half reactions.
