本書序言
●CONCEPTUAL UNDERSTANDING: Conceptual learning and problem solving are fundamental to the approach of Chemistry. The text gives students the tools to become critical thinkers: to ask questions, to apply rules and models, and to evaluate the outcome.
●PROBLEM-SOLVING: This text talks to the student about how to approach and solve chemical problems, since one of the main goals of general chemistry is to help students become creative problem solvers. The authors emphasize a thoughtful, logical approach rather than simply memorizing procedures.
●DYNAMIC ART PROGRAM: Most of the glassware, orbitals, graphs, flowcharts, and molecules have been redrawn to better serve visual learners and enhance the textbook.
●REAL-WORLD APPLICATIONS: Interesting applications of modern chemistry show students the relevance of chemistry to their world.
●COMPREHENSIVE END-OF-CHAPTER PRACTICE AND REVIEW: This text offers end-of-chapter exercises for every type of student and for every kind of homework assignment, including an unparalleled variety of end-of-chapter content with problems that increase in rigor and integrate multiple concepts
本書特色
●We have added three new Sections to the text:
> 4.11: Simple Oxidation-Reduction Titrations
> 15.6: Polyprotic Acid TitrationK
> 17.5: Entropy Changes in Aqueous Ionic Solutions
●We have added several new subsections throughout the text:
> The Process ofHeat (in Section 6.1)
> Photoelectron Spectroscopy for Atoms (in Section 7.12)
> Photoelectron Spectroscopy for Molecules (in Section 9.3)
> Distinguishing Between Chemical and Physical Changes at the Molecular Level (in Section 10.1)
> Forces Between Polar and Nonpolar Molecules (in Section 10.1)
> Chromatography (in Section 11.2)
> Mechanisms with Past Forward and Reverse First Steps (in Section 12.5)
> Acid Catalysis (in Section 12.7)
> Nonspontaneous Reactions (in Section 17.7)
●In Chapter 3 the treatment of stoichiometry has been enhanced by a discussion of "BCA" (Before-Change-After) tables, which allow another method by which students can
conceptually understand the role coefficients play in a balanced chemicai 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.
●In Chapter 4 we expanded Section 4.10 to include the halfreaction method for balancing complex oxidation-reduction reactions. This change was made to better support typical
laboratory programs.
●New end-of-chapter questions and problems have been added throughout the text.
●The art program has been modified and updated as needed, and new macro/micro illustrations have been added.
