E cell chemistry
could you plz teach me which one is correct
E cell = E oxidation + E reduction
or
E cell = E reduction - E oxidation
and E cell = E Cathode - E Anode
is it correct?
E cell = E oxidation + E reduction
or
E cell = E reduction - E oxidation
and E cell = E Cathode - E Anode
is it correct?

I haven't taken A level chemistry in ages so let me just refresh but I remember it as Reduction was the Right electrode so it's E cell= E reduction - E oxidation
Ecell= E right hand side - E left hand side
The more positive half cell will always reduce (go forwards) and the more positive half cell will always reduce (go forwards)
Hope this helps

Looks like the electropotential series (standard potential series). This series is a redox reaction. The metal (or semi-metal) with the highest nobility is the reduction, while the one with the lesser nobility is the oxidation. In this calculation you subtract the potential of the lesser noble metal (oxidation) from the noblest one (reduction), so:
E cell = E reduction - E oxidation

It's very easy to remember. Just look at the letters!
Ecell = E(RED) - E(OX)
it spells RE-DOX
