Study Notes
Mixtures and Pure Substances
- Mixtures are combinations of two or more substances that can be physically separated.
- Pure substances consist of only one type of material, cannot be physically separated, and are categorized into elements and compounds.
Types of Mixtures
- Homogenous mixtures have a uniform composition, making different parts indistinguishable.
- Heterogenous mixtures contain visibly different components and do not have a uniform composition.
Elements and Compounds
- Elements are the simplest form of matter, consisting of a single type of atom and listed on the periodic table.
- Compounds are chemical combinations of two or more elements, represented by chemical formulas.
Solutions and Suspensions
- Solutions form when substances dissolve to create a homogenous mixture, with no visible particles and unable to be filtered.
- Suspensions are mixtures containing solid particles dispersed in a liquid, where the solid can be seen and may settle upon standing.
Examples of Mixtures
