Chemistry: A Molecular Approach with MasteringChemistry® Access Code (2nd Edition) (MasteringChemistry Series);

This innovative text explains difficult concepts in a relevant, student-oriented manner.  Chemistry is presented visually through multi-level images—macroscopic, molecular and symbolic representations—helping you see the connections among the formulas (symbolic), the world around you (macroscopic), and the atoms and molecules that make up the world (molecular). Among other revisions, the Second Edition offers a crisp new design, adds more challenging problems, and significantly revises coverage of electrochemistry. Used by over a million science students, the Mastering platform is the most effective and widely used online tutorial, homework, and assessment system for the sciences.
