THIS IS KINDA LONG BUT I NEED HELP PLEASE A spontaneous redox reaction happens between zinc (Zn) and magnesium (Mg) in an electrochemical cell.

Calculate the standard potential (voltage) of the cell. (1 point)

v. What kind of electrochemical cell is this? Explain your answer. (1 point)

b. A redox reaction occurs in an electrochemical cell, where silver (Ag) is oxidized and nickel (Ni) is reduced. (5 points)

i. Write the half-reactions for this reaction, indicating the oxidation half-reaction and the reduction half-reaction. (1 point)

Which metal is the anode, and which is the cathode? (1 point)

iii. Calculate the standard potential (voltage) of the cell. (2 point)

iv. What kind of electrochemical cell is this? Explain your answer. (1 point)
