Question

If a substance can be separated by physical means and it is not the same throughout, what is it?

A: a homogeneous solution

B: a heterogeneous mixture

C: a pure substance

D: an element

E: a compound

Answer 1

B: a heterogeneous mixture

Step-by-step explanation:

If the components of a substance can be separated by the physical means then the substance is a mixture and its component have not undergone any kind of chemical change with their original molecular structure.

The mixtures are of two types homogeneous and heterogeneous.

• Homogeneous mixtures have a uniform composition of its components throughout the mixture whereas heterogeneous mixtures have a non-uniform composition of its constituents in the mixture.

Answer 2

Option (B)

Step-by-step explanation:

A heterogeneous mixture is usually defined as a combination of two or more chemical substances. It can be also elements as well as compounds. These contrasting components can be easily separated from one another by means of physical process. These are comprised of substances that are not even everywhere. There is variation in it.

Thus, the correct answer is option (B).
