Answer:Mixtures have several general properties: they are made up of two or more substances physically combined, the components retain their original properties, they can be separated by physical means, and they have variable composition. These properties are very useful in real-life situations. For example, the fact that mixtures can be separated helps in recycling materials like plastics and metals. In cooking, ingredients are mixed but still keep their original taste and texture, making it easier to adjust flavors. In medicine, mixtures like syrups and ointments allow combining substances without changing their effects. Because the substances in a mixture keep their identity, we can use and reuse them in different ways without losing their usefulness.
