Explanation:

Electrolysis has to do with the decomposition of a solution by the passage of direct current through it. Current enters and leaves the electrolyte via electrodes.

The positive electrode is called the anode while the negative electrode is called the cathode. Positive ions move towards the cathode while negative ions move towards the anode.

Cu^2+ moves towards the cathode and accepts two electrons to be deposited on the cathode as metallic copper. Also, Cl^- ions move towards the anode and gives up electrons to become oxidized to chlorine gas.

Hence in the electrolysis of CuCl2, copper is obtained at the cathode while chlorine gas is obtained at the anode. Hence 1 and 3 are correct statements.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
