1
Q
What cause electrons from one electrode to another
A
The electrons flow from a more reactive metal electrode to a less reactive metal electrode
2
Q
The ____ the two metal electrodes in the reactivity series, the greater the voltage of electric cell
A
further
3
Q
What will be observed over time for two metal electrodes?
A
More reactive metal become smaller over time as it was oxidised and less reactive metal become “larger” as electrolyte gets reduced and form atoms on the surface of the less reactive metal
