A redox reaction occurs in an electrochemical cell, where silver (Ag) is oxidized and nickel (Ni) is reduced. i. Write the half-reactions for this reaction, indicating the oxidation half-reaction and the reduction half-reaction.
ii. Which metal is the anode, and which is the cathode?
iii. Calculate the standard potential (voltage) of the cell.
iv. What kind of electrochemical cell is this?
I really cant find a answer and need help pls
