Question

what is heterogeneous mixture

Answer 1

A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties. In some mixtures, the initial substances cannot be detected after they have been mixed.

Answer 2

A heterogeneous mixture is a mixture having a non-uniform composition. The composition varies from one region to another, with at least two phases that remain separate from each other, with clearly identifiable properties. If you examine a sample of a heterogeneous mixture, you can see the separate components.
