Authors Steven and Susan Zumdahl offer all the elements instructors need for their general chemistry course. They bring a conceptual approach to chemistry and integrate problem-solving skills throughout, helping students transition from theory to practice. A strong emphasis on models, real-world applications, and visual learning prevails throughout the text. The Seventh Edition seamlessly integrates the strengths of the Zumdahl approach through a comprehensive and interwoven print and technology program. Enhanced Sample Exercises, online homework problems, and Classroom Response System content help instructors assess conceptual understanding and problem-solving skills, while new animations and images support visual learning. In addition, Houghton Mifflin offers implementation services through our TeamUP program to help instructors and students get the most out of the text and its supplements. New! Reality Checks at the end of selected Sample Exercises prompt students to ensure that their answers are reasonable. New! The expanded art program includes new electrostatic potential maps in Chapter 8, "Bonding" that illustrate bond and molecular polarity. New! The redesigned For Review section now includes bulleted key concepts for the chapter, as well as review questions of which approximately 50% are new. New! Integrative Problems in the end-of-chapter material assess students' cumulative understanding of multiple concepts and skills presented in previous chapters. End-of-chapter questions also include collaborative Active Learning Question (formerly In-Class Discussion Questions), Exercises organized by topic, Additional Exercises not keyed by topic, integrative Challenge Problems, and comprehensive Marathon Problems. New! Algorithmically-generated Test Questions as well as Conceptual Questions are available in HM Testing, all coded by level of difficulty to allow instructors to more easily choose appropriate test items. New! Animations with assignable exercises appear on the Online Study Center and Student CD. New! HM ClassPresent v.3 includes new animations and videos as well as enhanced search functionality. Eduspace Online Learning Tool features two kinds of problems: ChemWork interactive online homework and end-of-chapter algorithmic questions with links to corresponding textbook pages and media for student reference at point of learning.
