Based on the half-reactions shown, a chemist designs a galvanic cell. We are asked to write the balanced equations for the half-reactions at the cathode, anode, and overall reaction. And additionally, to calculate the cell voltage if possible.


Assuming the reaction is under acidic conditions, we will follow the following steps to balance the reactions:

Step 1: Separate the whole reaction into two half-reactions

Step 2: Balance the non-hydrogen and non-oxygen elements first

Step 3: Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

Step 4: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)
