(A chemist designs a galvanic cell that uses these two half-reactions: a)Write a balanced equation for the half-reaction that happens at the cathode. (b)Write a balanced equation for the half-reaction that happens at the anode. (c)Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written. (d)If you said it was possible to calculate the cell voltage, do so and enter your answer here. Round your answer to 2 significant digits. Please explain , give correct answer and typed answer only as I can not understand handwriting clearly
