Question

identify the characteristics of a mixture.
mark all correct answers
□ a. chemical reaction takes place.
□ b. not a pure form of substance.
□ c. components can be separated by physical methods.
□ d. may have uniform or non - uniform composition.

Explanation:

• Option a: Mixtures form without chemical reactions, so this is incorrect.
• Option b: Mixtures combine two+ substances, so they are not pure.
• Option c: Mixture components keep their properties, so they can be separated physically (e.g., filtration, evaporation).
• Option d: Homogeneous mixtures have uniform composition, heterogeneous ones do not, so this applies to mixtures.

Answer:

b. Not a pure form of substance.
c. Components can be separated by physical methods.
d. May have uniform or non-uniform composition.
