Although Chemical Principles is intended for students with solid mathematical preparation and prior exposure to chemistry, the author does not assume that students have a sophisticated grasp of chemical concepts.

• Approximately 20 percent of the boxed essays are new, presenting everyday applications of chemistry with an emphasis on engineering applications.
• To create more effective teaching tools, more than 100 illustrations—with a key focus on molecular-level illustrations—have been redone. Selected important equations have also been emphasized by highlighting them in color.
