Constituents of a mixture

• A. unite chemically in a fixed ratio
• B. can be separated by physical means
• C. retain their individual, physical and chemical properties
• D. can be present in any ratio

Answer 1

Answer: (B), (C), (D)

can be present in any ratio

• A mixture is formed when atoms or molecules of the same or different particles combine with each other physically. Hence, Option B is correct.
• For example - Air is a mixture of gases like Carbon dioxide, Nitrogen, Oxygen, etc; dust, Water vapors.
• The different substances that combine to form a mixture are constituents of the mixture or components of the mixture.
• Since, there is no chemical bond formation that takes place in a mixture, the constituents retain their physical and chemical properties. Hence, option C is correct.
• Option A is wrong because, in a mixture, constituents combine in any ratio, and Option D is correct.

Hence, Option B, C, and D are correct answers.
