According to Authors; A major new feature of this edition is the addition of a second Practice Exercise to accompany each Sample Exercise within the chapters. The majority of new Practice Exercises are of the multiple-choice variety, which enable feedback via MasteringChemistry. The correct answers to select Practice Exercises are given in an appendix, and guidance for correcting wrong answers is provided in MasteringChemistry. The new Practice Exercise feature adds to the aids provided to students for mastering the concepts advanced in the text and rectifying conceptual misunderstandings. The enlarged practice exercise materials also further cement the relationship of the text to the online learning materials. At the same time, they offer a new supportive learning experience for all students, regardless of whether the MasteringChemistry program is used.
