The author’s goal in writing this book is to deliver the depth of coverage faculty want with the accessibility and clarity that students need for success. Nivaldo J. Tro’s Chemistry: A Molecular Approach with MasteringChemistry®, 2/e explains difficult chemical concepts in a concise and clear student-centered manner while also providing faculty with the flexibility to go more deeply into many key, often neglected, topics such as electron diffraction, molecular orbital theory, and free-energy changes under non-standard conditions. Chemistry is presented visually through multi-level images (macroscopic, molecular and symbolic representations), which helps students see the connections among the formulas (symbolic), the world around them (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. Matter,...
