Homogeneous or Heterogeneous – Mixtures Practice Worksheet 3


Mixtures can be a confusing topic for new chemistry students. On the surface, mixtures do not seem all that complicated. A mixture is a collection of different materials. Take more than one thing, combine them and you have a mixture.

Mixtures can be further classified as either homogeneous or heterogeneous mixtures. A homogeneous mixture is a mixture where the combined components is uniformly distributed throughout the mixture in a single phase. A heterogeneous mixture is when the components are not uniformly distributed or contain more than one state of matter.

Sometimes, multiple components can be combined and not form mixtures. These combinations are called pure substances. These combinations can be separated as elements or compounds. Elements are combinations of atoms of the same element. Compounds are formed when atoms of different elements are combined.

This worksheet can help practice identifying heterogeneous and homogeneous mixtures or elements and compounds.
