CHEM101: General Chemistry I

4.1: Chemical Formulas

• 4.1.1: Empirical and Molecular Formulas

  • Khan Academy: "Empirical and Molecular Formulas Series" Page

    Watch these six videos, which will prepare you for the following reading assignment.
    

  • Stephen Lower's "General Chemistry Virtual Textbook: Chemical Formulas and Their Arithmetic"

    Read this webpage, which explains what information chemical formulas reveal and how to derive chemical equations from experimental data. This is one of the most math intensive units in General Chemistry, but it is not as tricky as it may seem at first. Follow the method.
    

• 4.1.2: Nomenclature

  • Stephen Lower's "General Chemistry Virtual Textbook: Naming Chemical Substances: Introduction to Chemical Nomenclature"

    Read this webpage. "Nomenclature" is a fancy word for the process of naming compounds. The more you practice systematically naming compounds, the easier it will become. Here, primarily inorganic substance nomenclature is covered. While organic nomenclature is introduced here, it will be covered in more detail in Organic Chemistry.
