General Chemistry: Principles and Modern Applications is recognized for its superior problems, lucid writing, precision of argument, and precise and detailed treatment of the subject. Popular and innovative features include Feature Problems, follow-up A and B Practice Exercises to accompany every in-chapter Example, Focus On application boxes, and new Keep in Mind marginal notes Features Problem Solving: Nobody knows problems like Ralph Petrucci. NEW! - Two-column Examples. Selected Examples are arranged in two-column format. A and B Practice Exercises-Follow most Worked Examples. The A practice exercise follows the worked model, but with new variables. The B practice exercise takes students further in their thinking about the same concept. Gives students a chance to build their understanding through additional practice of each problem type. Keep in Mind marginal notes-reminds students of ideas introduced earlier in the text that must be understood in relation to the subject at hand. Guided integrative exercises-includes worked examples of each so students build the necessary skills to solve these more challenging problems. Newly organized in a three-part Strategy/Solution/Assessment format, these exercises integrate concepts presented within the chapter and, to the extent possible, from earlier chapters. The Assessment feature shows the relevance of the example to important matters discussed in the chapter or elsewhere in the text. Diverse, thought-provoking end-of-chapter exercises-Include basic categorized problems ranging up to the most challenging problems which require the highest order of thinking. Includes new exercises called Self-Assessment Exercises. These will resemble questions that might be posed in quizzes or examinations. Enhanced Conceptualization NEW - Concept Assessment questions. About 5 - 8 of these questions per chapter challenge students' understanding of the subject matter have been added at appropriate points. For example, in the equilibrium chapter (Chapter 15) students are asked to draw several pictures that represent the ratio of products to reactants for specific equilibrium constants NEW - Concept Maps. The notion of concept maps will be introduced and illustrated in a new Appendix in PHHM 9/e. One or more of the Self-Assessment Exercises in each chapter will require students to construct a concept map. NEW format for end-of-chapter Summaries. These will be subdivided according to chapter sections. Each section will incorporate Key Terms introduced in that section and will include references to key equations, tables, and equations. Visualization Illustrations. There will be a fair number of new art pieces such as a large increase in the number of electrostatic potential maps. New micro-macro illustrations are being added where needed. Provoking Thought Are You Wondering?-These popular boxes ask and answer questions that would arise from a careful reading of the material. These boxes address the needs of the brightest students by intercepting common questions, and they stimulate further thinking and critical reasoning skills in general.
