Answer

Brief Explanations:

A heterogeneous mixture consists of two or more pure substances that are not chemically bonded and have a non - uniform appearance. Components of a heterogeneous mixture can be separated physically, and there are no fixed ratios between components. Chemical bonding and uniform appearance are characteristics of homogeneous mixtures or compounds.
