Need a chemistry textbook you can actually understand? CHEMISTRY starts with the basics and illustrates as it goes so you'll be able to follow each concept fully. Plus, this edition has a full online course available in OWL (Online Web-based Learning), a flexible web-based homework management system complete with simulations and tutorial. Available separately. OWL also includes several Go Chemistry™, mini video lectures for key concept review and exam prep that you can view in OWL, download to your desktop, or import to your portable video player to study on the go!
