Here's why:
* No new substances are formed: In a mixture, the original substances retain their individual chemical properties. They simply combine physically.
* Components can be separated: The components of a mixture can usually be separated using physical methods like filtration, evaporation, or magnetism.
* Variable composition: Mixtures can have varying proportions of their components.
Examples of mixtures:
* Salt and pepper: You can easily see the individual grains of salt and pepper.
* Air: A mixture of gases like nitrogen, oxygen, and carbon dioxide.
* Sand and water: The sand settles to the bottom, while the water remains liquid.
