Understand the definitions of the terms given: A compound is a substance formed when two or more elements chemically combine in fixed proportions.
An element is a pure substance consisting of only one type of atom.
A homogeneous mixture is a mixture that has a uniform composition and appearance throughout, meaning you cannot distinguish different parts.
A heterogeneous mixture is a mixture where the components are not uniformly distributed, so different parts of the mixture can be observed.
Since the question asks for a mixture that is not uniform throughout, the correct term is 'heterogeneous mixture'.
