What is the correct characteristic of a heterogeneous mixture?

Answer and explanation

Correct answer: It has different compositions in different parts.

A heterogeneous mixture has a non-uniform composition, so different portions of the sample may contain different amounts or kinds of its components. For example, in sand mixed with water, the sand and water can be distinguished and a sample taken from one region may not have the same composition as a sample from another. Therefore option B is correct. A completely uniform composition describes a homogeneous mixture, not a heterogeneous one. A mixture may contain several elements or compounds, so it is not limited to one element. Also, mixtures do not have a fixed chemical formula because their component proportions can vary; a fixed formula is characteristic of a pure compound.
