A mixture is a combination of two or more substances that retain their individual properties and can be separated by physical means. Mixtures can include solids, liquids, and gases. They are classified into two main types:
1. **Homogeneous Mixtures**: These mixtures have a uniform composition throughout, meaning that the individual components are not easily distinguishable. An example is a solution like saltwater, where the salt is completely dissolved in water.
2. **Heterogeneous Mixtures**: In these mixtures, the components are not uniformly distributed, and you can often see the different parts. For instance, a salad or a mixture of sand and gravel would be considered heterogeneous.
Mixtures contrast with compounds, which are substances formed when two or more elements chemically bond to form a new substance with distinct properties.
