Study Notes
Mixtures
- A blend of two or more substances, each retaining their individual properties.
- Substances in a mixture do not undergo chemical reactions.
Classification of Matter
- Matter is the fundamental building block of the universe.
- Mixtures are combinations of substances where each substance retains its original properties.
- Homogeneous mixtures have a uniform composition throughout.
- Heterogeneous mixtures have a non-uniform composition throughout.
- Pure Substances are composed of a single type of matter.
- Elements are the simplest pure substances, appearing on the periodic table.
- Compounds are formed when two or more elements combine chemically.
Types of Mixtures
- Homogeneous Mixtures (also called solutions) have uniform composition and properties throughout, making them indistinguishable.
- Prepared through physical processes and can be separated physically.
- Heterogeneous Mixtures exhibit a non-uniform composition, with identifiable distinct components.
- Possess a non-uniform distribution of components.
