7. A voltaic cell is assembled with Pb(s) and Pb(NO3),(aq) in one compartment and Zn(s) and ZnCl,(aq) in the other. An external wire connects the two electrodes, and a salt bridge containing KNO,(aq) connects the two solutions. a) In the product-favored reaction, zinc metal is oxidized to Zn2+. Write a balanced net ionic equation for this reaction. b) Which half-reaction occurs at each electrode? Which is the anode and which is the cathode? c) Draw a diagram of the cell, indicating the direction of electron flow outside the cell and of ion flow within the cell.
