Chemical principles

This fully updated Seventh Edition of CHEMICAL PRINCIPLES provides a unique organization and a rigorous but understandable introduction to chemistry that emphasizes conceptual understanding and the importance of models. Known for helping students develop a qualitative, conceptual foundation that gets them thinking like chemists, this market-leading text is designed for students with solid mathematical preparation. The Seventh Edition features a new section on "Learning to Solve Problems" that discusses how to solve problems in a flexible, creative way based on understanding the fundamental ideas of chemistry and asking and answering key questions. The book is also enhanced by new visual problems, new student learning aids, new Chemical Insights boxes, and more. Features: -- Unique Organization: The authors cover equilibria and acid-base chemistry early and delay coverage of atomic theory and bonding until the second half of the text. The text includes sections on Exact Treatment of Buffered Solutions (Chapter 8), Adiabatic Processes (Chapter 10), and Molecular, Rotational, Vibrational, Electronic, and Nuclear Magnetic Spectroscopy (Chapter 14). These sections provide more depth at a slightly more rigorous level, consistent with the book's overall focus. -- Wide Range of End-of-Chapter Questions. The Seventh Edition includes Discussion Questions, Exercises, integrative Challenge Problems, and comprehensive Marathon Problems. -- Chemistry Explorer Boxes. These boxes profile chemistry professors who currently are pioneering research in their fields and introduce students to today's role models in chemical research. Topics include "The Structures of Nucleic Acids," "Studying the Chemistry of Earth's Atmosphere," "The Role of Metals in Biological Systems," "Ultrafast X-ray Spectroscopy," and many others. -- Mathematical Support. All mathematical operations required for the text are conveniently described in an Appendix or are illustrated in worked-out examples. Knowledge of calculus is not required, and differential and integral notations, used only where absolutely necessary, are accompanied by explanations. -- Online ChemWork Exercises: ChemWork assignments developed by Steven and Susan Zumdahl coach students through the process of becoming independent problem solvers. Available online within OWL and Enhanced WebAssign, ChemWork exercises provide students with challenging problems with hints for practicing concepts from the chapter. Publisher's note.
