This course builds a quantitative foundation for general chemistry through measurement, units, dimensional analysis, and significant figures, emphasizing reliable multi-step calculation setup. Core atomic theory is developed from subatomic structure through electron configurations and periodic trends explained by effective nuclear charge. Chemical bonding and molecular structure are treated via Lewis structures, formal charge (intro), resonance (intro), VSEPR, polarity, and intermolecular forces linked to macroscopic properties. Reaction chemistry centers on balancing equations, stoichiometry, limiting reactants, and yields, then extends to gases, phase behavior, solutions and molarity-based calculations, introductory equilibrium and acid–base concepts, and thermochemistry/intro thermodynamics using calorimetry and enthalpy.
