I got 134.91 but if you round it you’ll get 135
Carbon can go either way they can have a 4+ charge (by losing 4 electrons) or a 4- charge (by gaining 4 electrons) to fulfill the octet rule.
The process that occurs at the anode in an
electrochemical cell is the loss of electrons. The answer is number 2. Oxidation occurs as electrons are lost at the
anode at one of the electrodes in both an electrolytic cell and a
voltaic cell.
The answer is D :) have a nice day!
