General Chemistry Courses provide an introduction to the fundamental principles of chemistry. Topics include: atoms and molecules; periodicity, bonding and molecular structure; intermolecular forces; properties of solids; liquids, gases and solutions；stoichiometry and introduction to reactions in aqueous solutions; infrared spectroscopy, and mass spectrometry; thermochemistry and the first law of thermodynamics; quantum aspects of light and matter; and bonding in diatomic and polyatomic molecules. Laboratory exercises include: the size of an atom, qualitative analysis, thermochemistry, and quantum aspects of light and matter.
