Consider the following statements regarding matter:
- 1Elements cannot be broken down into simpler substances.
- 2A compound has variable composition and can be broken down into elements.
- 3The solution of sulphur in carbon disulphide is an example of a homogeneous mixture.

General KnowledgeChemistry
- A2 only
- B1 and 3
- C3 only
- D1 and 2
Explanation
The question asks which statements are not correct. Statement 1 is correct: elements cannot be broken down into simpler substances by chemical means. Statement 2 is not correct: a compound has a fixed (not variable) composition, though it can indeed be broken down into its constituent elements. Statement 3 is correct: sulphur dissolved in carbon disulphide is a homogeneous mixture. Hence only statement 2 is not correct.
