Adapted from Nivaldo J. Tro’s best-selling general chemistry text, Principles of Chemistry: A Molecular Approachfocuses exclusively on the core concepts of general chemistry without sacrificing depth or relevance. Tro's unprecedented two- and three-column problem-solving approach is used throughout to give students sufficient practice in this fundamental skill. A unique integration of macroscopic, molecular, and symbolic illustrations help students to visualize the various dimensions of chemistry; and Tro’s engaging writing style captures student’s attention with relevant applications. The Second Editionoffers a wealth of new and revised problems, approximately 50 new conceptual connections, a new design and revised art program throughout. This edition features the exact same content as the traditional text in a convenient, three-hole- punched, loose-leaf version. Books la Carte also offer a great value – this format costs significantly less than a new textbook.
