Nickel can react with aqueous silver nitrate solution according to the following ionic equation: 

Ni(s) + 2 Ag⁺(aq) → 2 Ag(s) + Ni²⁺(aq) 

Assume the half-reactions are separated into two compartments. A Ni electrode is placed in a compartment with 1.00 M Ni(NO₃)₂, and a Ag electrode is placed in a compartment with 1.00 M AgNO₃. Indicate each of the following:

(a) Oxidation half-cell reaction

(b) Reduction half-cell reaction

(c) Anode and cathode

(d) Direction of electron flow

(e) Direction of NO₃^– in the salt bridge.
