General Chemistry I

Online Chemistry Course Overview

This course is designed to familiarize students with the basic principles of chemistry. The course begins with an analysis of matter and its components, stoichiometry, and intermolecular force and phase changes. Properties of liquids, solids, and gasses are also explored. This foundation is used to examine solubility, colligative properties of solutions, chemical reactions, quantum theory and atomic structure, and chemical periodicity. Other topics include main group and transition elements.

Do I have to buy the textbook?
As in many college courses, purchasing the book is ultimately up to you. The StraighterLine courses use reading assignments and practice work from the textbook as supplements, but you will not be required to turn in anything from the book. StraighterLine recommends that you purchase the appropriate text so you are equipped with as many resources as possible (please note that e-books are generally less expensive but may have slight differences in page numbers and resources compared to a hard copy text).
