Question

Which of these terms refers to matter that could be heterogeneous?
(1) element (3) compound(2) mixture (4) solution

Answer 1

Mixture. Mixtures can be both heterogeneous and homogeneous. Heterogeneous mixtures are mixtures that don't have a fixed composition, meaning that if you take smaller samples from two different parts of a larger sample, the ratios of the substances will differ.

Answer 2

Answer: Option (2) is the correct answer.

Explanation:

A mixture is a substance that contains two or more different substances mixed together.

A mixture can be homogeneous and heterogeneous mixture.

When the solute particles are uniformly dispersed into the solvent then it is known as a homogeneous mixture.

Whereas when the solute particles are non-uniformly dispersed into the solvent then it is known as a heterogeneous mixture.

On the other hand, a solution contains even distribution of dispersed particles   into the dispersion medium. A solution is a clear solution.

A compound is a substance that contains two or more different atoms which are chemically combined together. Whereas an element contains atoms of only one type.

Thus, we can conclude that mixture is the term that refers to matter that could be heterogeneous.
