a voltaic (galvanic) cell is sketched below. (a) write the balanced equations for the oxidation and reduction half-reactions taking place in the cell. (include states-of-matter under satp conditions in your answer.) oxidation half-reaction: chempadhelp reduction half-reaction: chempadhelp (b) identify the anode and cathode in the cell. anode: copper magnesium correct: your answer is correct. cathode: copper magnesium correct: your answer is correct. (c) write the balanced equation for the overall cell reaction. (include states-of-matter under satp conditions in your answer.) chempadhelp
