Introduction: The Basics of Chemistry – Molecules and Mixtures
- Definition of Molecules: A molecule is the smallest unit of a chemical compound that retains its chemical properties. It consists of atoms bonded together, and its behavior is influenced by its atomic structure and bonding.
- Definition of Mixtures: A mixture is a physical combination of two or more substances where each substance retains its chemical properties. Mixtures can be heterogeneous (not uniform) or homogeneous (uniform).
- Relevance of Chemical Formulas in Mixtures: Understanding the molecular structure of substances helps in predicting how they will behave in a mixture. The interactions between molecules determine the properties of the mixture, including its physical and chemical characteristics.
