Principles of Chemistry: A Molecular Approach, 4/e (IE-Paperback) (化學原理：分子方法（第4版）)

●NEW INTERACTIVE VIDEOS I have added 16 newKey Concept Videos (KCVs) and 24 new Interactive Worked Examples (IWEs) to the media package that accompaniesthe book. The video library now contains nearly 200 interactivevideos. These tools are designed to help professorsengage their students in active learning.
●NEW IN-CHAPTER QUESTIONS WITH FEEDBACK I have added approximately 67 new Conceptual Connectionquestions throughout the book and have changed theformat to multiple choice (with wrong answer feedbackin Mastering Chemistry). Each chapter now has 10-12 ofthese assignable questions. These questions transformthe reading process from passive to active and holdstudents accountable for reading assignments.
●NEW MISSED THIS? FEATURE I have added a newfeature called MISSED THIS? to the Self-AssessmentQuizzes and to the Problems by Topic section of the endof-chapter problems. This feature lists the resourcesthat students can use to learn how to answer thequestion or solve the problem. The resources includechapter sections to read, Key Concept Videos (KCVs) towatch, and Interactive Worked Examples (IWEs) to view.Students often try to solve anquestion orass~gnedproblem before doing any reading or reviewing; theyseek resources only after they have missed the questionor problem. The MISSED THIS? feature guidesthem to reliable resources that provide justcin-timeinstruction.
●NEW FOR PRACTICE FEEDBACK I have enhanced64 of the in-chapter For Practice problems (whichimmediately follow an in-chapter worked example)with feedback that can be accessed through MasteringChemistry.
●REVISED ART PROGRAM The art program has beenextensively revised.of the more complex figNav~gationureshas been reoriented to track from left to,right, andmany figure captions have been broken up and have beenmoved into the image itself as an "author voice" that exJ?lains the image and guides the reader through it.
●REVISED DATA INTERPRETATION AND ANALYSIS QUESTIONS The Data Interpretation and Analysisquestions that accompany each chapter have been extensivelyrevised to make them clearer and more accessibleto students.
●NEW SECTION ON DATA INTERPRETATION ANDANALYSIS I have added a new section to Chapter 1(Section 1.9) on the general topic of analyzing and interpretingdata. This section introduces the skills requiredto address many of the revised data interpretation andanalysis questions.
●NEW HOW TO . .. FEATURE All guidance for essentialskills such as problem-solving techniques, drawing Lewisstructures, and naming compounds is now presented ina consistent, step-by-step numbered list called How To ...
●REVISED CHAPTER 4 Chapter 4 in the previous editioncovered both stoichiometry and chemical reactionsin solution. In this edition, this content has been expanded slightly and has been divided into two morefocused chapters, so that Chapter 4 is now focused onstoichiometry and Chapter 5 on chemical reactions insolution. This new organization lessens the cognitiveload for students and allows each chapter to be moredirect and focused. All subsequent chapters have beenrenumbered accordingly.
●NEW ACTIVITY SERIES CONTENT I added a newsubsection to Section 5.9 entitled The Activity Series: PredictingWhether a Redox Reaction Is Spontaneous. The newsection includes new figures, tables, and a new workedexample.
●NEW READY-TO-GO LEARNING MODULES Theseonline modules offer students easy access to the bestTro content in Mastering Chemistry without needing tohave it assigned.
●NEW TWO-TIER OBJECTIVES A system of two-tierobjectives is being applied to the text and to the MasteringChemistry assets. The two tiers are Learning Objectives,or LOs, and Enabling Objectives, or EOs. The LOsare broad, high-level objectives that summarize the overalllearning goal, while the EOs are the building blockskills that enable students to achieve the LO. The learningobjectives are given in the Learning Outcomes tableat the end of the chapter.
●REVISED DATA All the data throughout the book havebeen updated to reflect the most recent measurementsavailable. These updates include Figure 4.2: CarbonDioxide in the Atmosphere; Figure 4.3: Global Temperatures;the unnumbered figure in Section 7.10 of U.S. Energy Consumption;Figure 7.12: Energy Consumption by Source; Table7.6: Changes in National Average Pollutant Levels,1990-Figure 15.19: Ozone Depletion in the Antarctic Spring;2016;Figure 17.15: Sources of U.S. Energy; Figure 17.16: Acid Rain;and Figure 17.18: U.S. Sulfur Dioxide Pollutant Levels.
●REVISEDCHAPTEROPENERS Manychapteropeningsections and (or) the corresponding art-includingChapters 1, 3, 4, 5, 6, 7, 10, 11, 18, 19, and 20-havebeen replaced or modified.
