Is this correct? Thanks.

What is the standard cell potential?
Pb2+ ( aq ) + 2e „³ Pb (s) -0.13V
Mn2+ ( aq ) + 2e „³ Mn (s) -1.19V

Pb2+ ( aq ) + 2e „³ Pb (s) -0.13V
Mn (s) „³ Mn2+ ( aq ) + 2e ¡V +1.19V


The electrode potential for a given cell,
E = Ecathode ¡V Eanode = -0.13 ¡V(-1.19) = +1.06 V




I don't understand some of the symbols.
