Introduction
Organization of the Course
The course has two major sections. The first half of the course covers the topics of measurement, matter, atomic structure, electrons, the periodic table, ionic and covalent bonding, and chemical reactions. The second half of the course covers the topics of moles, stoichiometry, states of matter, gases, mixtures, and solutions.
