Study Notes
Mixtures
- Mixtures are combinations of two or more substances that are not chemically bonded.
- Substances in a mixture retain their individual properties.
- Examples include sand and water, where sand remains sand and water remains water.
- Mixtures can be separated by physical methods like filtration, freezing, and distillation.
- These methods work because the substances are not chemically bonded.
Types of Mixtures
- Homogeneous Mixtures: Have uniform properties and composition throughout.
- Example: Salt dissolved in water.
- Heterogeneous Mixtures: Have varying properties and compositions in different parts.
- Example: Sand mixed with water.
Examples of Mixtures
- Air is a mixture of gases (oxygen, nitrogen, carbon dioxide).
- Seawater is a mixture of salt and water.
- Blood is a mixture of cells and fluids.
