Study Notes
Classification of Matter
- Matter is divided into two main categories: mixtures and pure substances.
Mixtures
- Mixtures are further classified into heterogeneous and homogeneous types.
- Mixtures consist of two or more pure substances that can be separated by physical means.
Heterogeneous vs. Homogeneous Mixtures
- Heterogeneous mixtures have two or more distinct phases, allowing for visible separation.
- Homogeneous mixtures, also known as solutions, consist of a single phase where components are uniformly distributed.
Pure Substances
- Pure substances fall into two categories: elements and compounds.
Elements
- Elements are represented by chemical symbols and are made up of atoms.
- The chemical symbol for carbon is C, and for oxygen, it is O.
- Oxygen occurs as O2, indicating that it consists of two atoms.
- Elements are defined by their atomic structure and cannot be broken down further.
Compounds
- Compounds are represented by chemical formulas and are composed of molecules.
- Common examples of chemical formulas include sodium chloride (NaCl) for salt and water (H2O).
- Molecules in compounds can be broken down into atoms through chemical changes.
