Heterogeneous chemical mixtures

Heterogeneous chemical mixtures are combinations of substances that do not have a uniform composition throughout. In such mixtures, the different components can often be distinguished from one another, both visually and physically. This means that the various parts of the mixture can be observed as separate entities, and their proportions may vary from one part of the mixture to another. Examples of heterogeneous mixtures include: 1. **Salad**: Various ingredients like lettuce, tomatoes, cucumbers, and dressing remain distinct.
