  • Steven S. Zumdahl

    Steve Zumdahl is the author of market-leading textbooks in introductory chemistry, general chemistry, honors-level chemistry, and high school chemistry. Recently retired from his long-time position as Director of Undergraduate Programs at the University of Illinois, he has received numerous awards for his contributions to chemical education. These include the National Catalyst Award in recognition of his contribution to chemical education, the University of Illinois Teaching Award, the UIUC Liberal Arts and Sciences Advising Award, and the School of Chemical Sciences Teaching Award (five times). He earned his B.S. in Chemistry from Wheaton College (IL), and his Ph.D. from the University of Illinois.

  • Donald J. DeCoste

    Donald J. DeCoste is Associate Director of General Chemistry at the University of Illinois, Urbana–Champaign and has been teaching chemistry at the high school and college levels for 26 years. He earned his BS in Chemistry and PhD from the University of Illinois, Urbana–Champaign. At UIUC he has developed chemistry courses for nonscience majors, preservice secondary teachers, and preservice elementary teachers. He teaches courses in introductory chemistry and the teaching of chemistry and has received the School of Chemical Sciences Teaching Award four times. Don has led workshops for secondary teachers and graduate student teaching assistants, discussing the methods and benefits of getting students more actively involved in class. When not involved in teaching and advising, Don enjoys spending time with his wife and three children.

  • A modified and updated full-color art program now better serves visual learners. In addition, the art has been reconfigured for better clarity, glassware illustrations have been updated, and the orbital art has been redesigned. Many new photos provide a contemporary look and increase the book’s relevance.

  • Over 10% of the end-of-chapter questions have been revised.

  • New Adaptive Learning Activities available online in OWLv2 are designed to deliver continuous, personalized support in manageable chunks throughout the learning process.

  • The treatment of stoichiometry in Chapters 9 and 15 now includes “BCA” (Before-Change-After) tables to give students another method to conceptually understand the role coefficients play in a balanced chemical reaction. Students are shown three methods to select a limiting reactant: comparing the amounts of reactant present, calculating the amounts of products that can be formed by complete consumption of each reactant, and using a BCA table. By thinking about a problem from various perspectives, students are encouraged to think about the fundamental conceptual aspects.

  • The text's hallmark problem-solving pedagogy is enhanced by in-text examples that suggest what questions the students should be asking as they solve problems.

  • Almost all of the in-text examples are "Interactive Examples" and available online in OWLv2. These examples require students to think through the example step-by-step, rather than simply scanning the written example in the text as many students do.

  • Point-of-use "Critical Thinking" boxes emphasize the importance of conceptual learning and are particularly useful for generating class discussion.

  • Section 8.4, "Learning to Solve Problems," is written specifically to help students better understand how to think their way through a problem.

  • ChemWork problems are available in the end-of-chapter problems throughout the text and as interactive tutorials in OWLv2.
