Answer: Option (B) is the correct answer.
Explanation:
A pure substance is defined as the substance that contains either same or different type of atoms that are chemically combined to each other in a fixed ratio by mass.
For example, both and
are pure substances.
A pure substance can only be separated by chemical means.
Whereas a mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.
For example, salt in water is a mixture.
In a mixture, solute particles can be either evenly or unevenly distributed in the solvent.
A mixture will always be separated by only physical means.
Thus, we can conclude that a pure substance different from a mixture as mixtures are made up of more than one component.
