Cathode = -ve and Anode = +ve 3 of 9 What are the reactions of the electrolysis of Copper(II) sulfate equations 4 of 9 Why cant an ionic solid be electrolysed? how can it be? An ionic solid can't be electrolysed because the electrons arent free to move, in order for it to be electrolysed it must be in a molten state 5 of 9 What is the equation for charge? Charge (columbs) = Current (Amps) X Time (Secs) OR Q=It 6 of 9 What is a fuel cell? a cell that is supplied with oxygen and a fuel, and uses the energy from the reaction to produce electrical energy 7 of 9 What are the reactions at the cathode and anode for a Hydrogen-Oxygen fuel cell diagram 8 of 9 What are the reactions for the depletion from the ozone layer from CFC's? equations 9 of 9
