PREFACE xv emphasize fundamental, vitally important principles of chemistry. Setting them apart visually makes them easier to find and revisit as needed throughout the course term. Each Visualizing Chemistry feature concludes with a “What’s the Point?” box that emphasizes the correct take-away message. There is a series of conceptual end-of-chapter problems for each Visualizing Chemistry piece. The answers to the Visualizing Chemistry problems, Key Skills problems, and all odd-numbered end of chapter Problems can be found in the Answer Appendix at the end of the text. These problems have been incorporated into the online homework and allow students to assess their understanding of the principles in each piece. Flow Charts and a variety of inter-textual materials such as Rewind and Fast Forward Buttons and Section Review are meant to enhance student understanding and comprehension by reinforcing current concepts and connecting new concepts to those covered in other parts of the text. Media. Many Visualizing Chemistry pieces have been made into captivating and pedagogicallyeffective animations for additional reinforcement of subject matter first encountered in the textbook. Each Visualizing Chemistry animation is noted by an icon. Integration of Electronic Homework. You will find the electronic homework integrated into the text in numerous places. All Practice Problem B’s are available in our electronic homework program for practice or assignments. A large number of the end-of-chapter problems and animations are in the electronic homework system ready to assign to students. For us, this text will always remain a work in progress.
