* No new substances are formed. The original substances retain their individual properties.

* The components can be separated by physical means. Examples include filtration, evaporation, distillation, or magnetism.

Here are some key points to remember about mixtures:

* Heterogeneous mixtures: The components are not evenly distributed throughout the mixture. You can see the different parts. (Example: sand and water)

* Homogeneous mixtures (solutions): The components are evenly distributed throughout the mixture. You can't see the different parts. (Example: salt water)

Let me know if you'd like me to elaborate on any of these points!
