Question

How is a mixture different from a pure substance?

A) Mixtures can be separated by physical means.
B) A pure substance is heterogeneous.
C) Pure substances are made up of mixtures.
D) A mixture is made of one substance.

Answer 1

The answer is A) Mixtures can be separated by physical means.

Answer 2

I think it’s A because a mixture is made up of multiple matters so D is incorrect, C is a single kind of matter, meaning it cannot be made of different mixtures so thats also incorrect. B is also incorrect because heterogeneous is a fancy way of saying “mixture”, therefore it would be incorrect. A is correct because mixtures can be separated i ways such as evaporation, distillation, and etc.
