Explanation:
This diagram demonstrates that both mixtures and compounds are made up of two or more substances. However, their key differences lie in how the substances are combined and the properties of the resulting mixture or compound.
Mixtures are simply physical combinations of substances, where each substance retains its original properties. They can be easily separated by physical means, such as filtration, evaporation, or magnetism. The composition of a mixture is not fixed and can vary depending on the proportions of the components.
Compounds, on the other hand, involve a chemical combination of substances. The substances react chemically to form a new substance with entirely different properties. These properties are distinct from those of the original components. Separating compounds requires chemical reactions, and their composition is fixed.
The diagram visually illustrates these key differences and the shared characteristic of being formed from multiple substances.
