Expert Solution

Give an example of a homogeneous mixture:

"WATER, because it is made up of two different elements - hydrogen and oxygen, and the composition is even throughout."

Which aspect of the student’s answer are correct? Which are incorrect?

Ans. Water is made up of two different elements and the composition of even throughout- correct.

However, water is a “compound”, NOT a “mixture”.

A mixture shows the property of all of its constituents. For example, if water were a mixture of hydrogen and oxygen- could be able to ignite water- because hydrogen is highly combustible and oxygen helps in combustion. But this is not true, water does not catch fire.

Water is a compound- a chemical entity consisting of two or more chemically-linked atoms, and exhibiting a unique property different from its constituents.

Therefore, water is NOT a mixture of hydrogen and oxygen, it’s a compound.

Since water is a compound, it is treated as a single entity. To make mixture, you require at least two different entities.
