The tenth edition of Steve and Susan Zumdahl's widely regarded CHEMISTRY combines a robust conceptual framework, a readable and engaging writing style, and an unparalleled selection of problems and exercises that make it one of the most trusted chemistry textbooks available today. CHEMISTRY uses a thoughtful approach built on creative problem-solving techniques and critical thinking. An emphasis on modeling and interactive examples helps students learn how to approach and solve chemical problems—to think like chemists—so that they can apply the process of problem solving to all aspects of their lives. Zumdahl and Zumdahl—and new coauthor Don DeCoste—students the tools they need to become critical thinkers: solve problems, apply chemical theories, and evaluate outcomes. The WebAssign component for this title links to a complete eBook and engages students with interactive tools such as chemPad and Marvin JS.

Also available to adopters is an additional collection of almost 1,400 questions that feature feedback, tutorials, and Deep Help. This collection is organized to match the table of contents of Zumdahl's CHEMISTRY, 10th edition, and can be added from "Free Additional Content" when creating your WebAssign course at no additional cost.

Use the Textbook Edition Upgrade Tool to automatically update all of your assignments from the 8th edition to corresponding questions in this textbook.
