Is mouthwash an element, a compound, a homogeneous mixture, or a heterogeneous mixture?

Option (c) is the correct answer.

Explanation:

An element is defined as a substance which cannot be broken down into simpler substances.

For example, potassium is a metal and it contains only atoms of potassium.

A compound is defined as a substance that contains two different elements which are chemically combined together in a fixed ratio by mass.

For example, is a compound in which atoms are present in 1:2 ratio.

A mixture in which particles of one or more number of solutes are evenly distributed into the solvent is known as a homogeneous mixture.

For example, a mouthwash is a homogeneous mixture because it is a clear solution as all the components are evenly distributed.

On the other hand, a heterogeneous mixture is defined as the mixture in which solvent particles are unevenly distributed into the solvent.

For example, mud particles present in water is a heterogeneous mixture.

Thus, we can conclude that mouthwash is a homogeneous mixture.
