Answer 1

Answer:

Question is not clear mate

Answer 2

Option A is the correct answer.

• Separation of chemical compounds is a dangerous process if the nature of the chemicals is unknown as each chemical behaves and reacts in a varied manner.
• Here chemical X is an ionic compound which means it should be able to react and interact with water as it is a universal solvent. Thus providing a safe and easy way of separation.
• Chemical Y is a covalent compound which suggests that it can interact more freely with ethanol or alcohol thus enabling dissolution/reaction ensuring another feasible method of separation.
