Answer 1

Answer:

sorry!!! the question is not clear

Explanation:

there is no figure

Answer 2

Coating of silver on iron ring is electroplating

Explanation:

• Deposition of a thin film of metal like gold , silver , chromium , nickel on another metallic article with the help of electricity is referred to as electroplating.
• The energy change happening here is the conversion of electric energy to chemical energy.
• In the process of electroplating the electrons are removed from one of the metals and in this case $Ag^+$ ions are formed. The process is referred to as oxidation which occurs at the anode. The metal attains a charge and dissolves in the electrolyte. Reduction occurs at the cathode as the metal turns into a neutral atom and attaches to the metal surface.
