the standard electrode potential for the following half reactions are
Zn(s) -----> (Zn^2 ) 2e^- (aq) E= -0.76v

Cu^2 (aq) . 2e^- ----> Cu(s). E= 0.34v

(I) calculate the standard electrode potential for the forward reaction
Zn(s) Cu^2 (aq) ---> Zn^2 (aq) Cu(s)
(II) on the basis of your answer to (I) is the forward reaction spontaneous? give reason for your answer
(III)distinguish between an electrolyte cell and an electrochemical cell
(IV) what are ores list three methods of extraction of metals from their ores?
