本書序言

> Core Text-All chapters were reviewed for clarity, enhanced understanding, and cohesive flow. Many sections were also revised as needed to help enhance the atoms firs temphasis throughout the textbook.
> Energy-An increased discussion of energy is included in the Review chapter (Chapter R). This includes discussions of the concepts of endothermic, exothermic, system, surroundings, and chemical energy.
> Chemistry Pioneers-A new boxed feature "Chemistry Pioneers" contains historical background on many earlychemists.
> Bond Energy-We have moved the bond energy discussion from the bonding chapter to the energy chapter. In this way we are able to more coherently discuss different methodsfor determining the enthalpy change for a reaction. We also provide a direct comparison of using bond energies and standard enthalpies of formations for determining the enthalpy of a given reaction and discuss the results.
> Liquids and Solids-Chapter 9 has been reorganized so tha tthe discussion of vapor pressure and phase diagrams comes immediately after the discussion of liquids. This makes for a smoother transition to discussing phase changes.
> Chem Work Problems-All of end of chapter problems were converted into ChemWork problems. These multiconcept problems (and additional ones) are found interactively online with the same type of assistance a student would get from an instructor.

本書特色

●EXPANDED TOPICS: The discussion of energy, for example, was expanded to support content referencing energy that appears before chapter 7.
●REORGANIZED END-OF-CHAPTER QUESTIONS support the special attention paid to the fluidity of topics relative to learning through the atoms first approach.
●REACTION ENTHALPY ESTIMATIONS from bond enthalpy was moved from chapter 3 to chapter 7 so that it appears after students have studied reactions in more detail.
●INCREASED CLARITY: Since nomenclature appears in later chapters, both formulas and names of molecules are referenced to not assume students have a prior knowledge of nomenclature.
●LADDERED ASSESSMENT SETS: Laddered Assessments are new assignment sets in OWLv2 that combine conceptual modules with more traditional homework questions. This provides students a structured learning path to bolster their skills. Students start with conceptual exercises like tutorials and simulations, then practice single concepts and skills in Mastery, then finally practice application in end-of-chapter exercises.
●IMPROVED FLUIDITY OF TOPICS ensures clarity, enhanced understanding and cohesive flow in every chapter. In areas such as measurements, calculations, and bonding, for example, the authors focus on increasing student comprehension of terms relative to placement of concepts as they proceed through the atoms first approach.
●ENHANCED CONTENT IN OWLv2: The enhanced content in OWL provides intentional, targeted guidance with a wider range of answer specific feedback, point-of-use remediation, and streamlined course templates.
●IMPROVED CONTEXT: Reminder call-outs were added to help students identify information from previous chapters to trigger a refresh of topics or remediation.
