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

hii umm i need help with dat

Explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
