Answer

Explanation:

Step1: Analyze boiling - point and residue

The boiling point is not the fixed boiling - point of pure water ($100^{\circ}C$) and a solid residue is left after boiling.

Step2: Recall substance classification

A pure substance has a fixed boiling - point and does not leave a residue after boiling. A mixture can have a non - fixed boiling - point and can leave a residue.

Answer:

Mixture; can be separated
