What is a key difference between an electrolytic cell and a voltaic cell A) The anode is assigned the negative charge. B) The anode is assigned the positive charge. C) The electrodes are connected with a wire. D) The electrons move from the anode to the cathode. E) There are two half-reactions.
The answer is D I believe. But that only depends on whether you differing the voltaic cell from the electrolytic cell, not the other way around, because only in a voltaic cell does move from anode to cathode.
