A chemist designs a galvanic cell that uses these two half-reactions: half-reaction 2+ MnO2(s)+4H (aq)+2e → Mn (aq)+2 H₂O(1) 2+ Zn(aq) + 2e ->>> Zn(s) standard reduction potential E = +1.23 V red = -0.763 V red Answer the following questions about this cell. Write a balanced equation for the half-reaction that happens at the cathode. Write a balanced equation for the half-reaction that happens at the anode. Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written. ☐ Do you have enough O Yes information to calculate the cell voltage under standard conditions? O No If you said it was possible to calculate the cell voltage, do so and enter your answer here. Round your answer to 3 significant digits. Ον ローロ e x10 ×
