Interpretation:Whether the clear liquid in a given scenario is an element, a compound, or a mixture should be identified.
Concept Introduction:A compound that is made up of two or more chemical components that are not chemically linked with each other is said to be a mixture.
The simplest form of matter consisting unique set of properties is said to be elements. They are pure substances made up of only one type of atom.
The chemical combination of two or more elements in a fixed proportion results in the formation of a compound.

Answer to Problem 21SP
It is a mixture.
Explanation of Solution
Given information:
Allowing a clear liquid to evaporate in an open container A,the solid remains in the container after three days.
The liquid present in container A cannot bond chemically after three days and form a compound. Also, it is not an element as the solid is observed after evaporation so the liquid in container A cannot be a pure substance that is made up of only one type of atom.
Since only solid remains after three days in container A so, it is a mixture.
