Solution
Answer 14.
In a redox reaction, reducing agent is the one reduces the other elements and itself gets oxidized. Here, Mg(s) is the one who reduces Sn +2 to Sn while itself is getting oxidized to Mg +2 .
Option B.
Answer 15.
Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell. Here,
Zinc is getting oxidized at Anode while Cadmium is getting reduced at Cathode. ( Anode - Oxidation while Cathode- Reduction). Therefore, electrons flow from Zn electrode to Cd electrode.
Option D.
