Please help! 35 points for a valid answer! how is the potential (voltage) of a redox reaction determined using the reduction potential chart calculate the voltage for the equation in 3(a)

Oxidation  half  reaction  is  written   as    follows when  using  using  reduction potential  chart

example  when  using  copper  it is  written  as  follows

CU2+   +2e-  --> c(s)  +0.34v

oxidasation  is the  loos  of  electron  hence copper oxidation  potential  is  as  follows

cu (s)  -->  CU2+   +2e    -0.34v

Explanation:

c) should be the answer.
