Introductory Chemistry, Third Edition helps students master the quantitative skills and conceptual understanding they need to gain a deep understanding of chemistry. Unlike other books on the market that emphasize rote memory of problem-solving algorithms, Introductory Chemistry takes a conceptual approach with the idea that focusing on the concepts behind chemical equations helps students become more proficient problem solvers. The Third Edition retains the engaging narrative and stunning illustrations that have made Russo/Silver so popular with students, while adding a powerful new media package and expanded problem-solving pedagogy designed to help students master the material. An Audible® MP3 workbook allows busy students to study on the go, interactive "clicker" questions written specifically for the Third Edition enable faculty to quiz and test students during lecture, and InterAct Math exercises on the text-specific website help students get up to speed on important quantitative topics. New end-of-chapter visualization and group problems foster student understanding and collaboration, while hundreds of new worked examples and problems provide students more practice opportunity than ever before. The text focuses students on comprehension of the core concepts as the basis for solving quantitative and qualitative problems and frees students from dependence on rote mathematical manipulation. WorkPatches and Practice Problems break students out of passive learning. Built into the narrative, WorkPatches require students to practice their understanding of key concepts, for example drawing a picture of what is happening on the molecular level. Practice Problems strengthen students' grasp of mathematical and problem-solving skills before they continue to new material. Problem Solving Guide and Workbook features 350 additional problems and worked examples, as well as a comprehensive math review, for even more student practice. Skills to Know feature summarizes the quantitative and problem-solving skills covered in each chapter and includes worked examples. End-of-chapter material features hundreds of problems, including a section of problems that synthesizes material across chapters. Comprehensive media package features a text-specific web site that enhances learning in and outside the classroom. The Chemistry Place (www.aw-bc.com/chemplace) offers tutorials, tools, quizzing, and animations for students and course management capabilities for instructors. The Instructor Resource CD-ROM for Introductory Chemistry provides figures from the text and additional animations for instruction. Abundant atomic and molecular depictions embedded into the narrative help students visualize concepts. Applications are woven directly into the text's conversational narrative, to evoke powerful images in the students' minds and help them grasp and retain concepts. Examples from such areas as nutrition, the atmosphere, DNA modification, and corrosion, show that chemistry is a fascinating science. Organic and biological examples important to allied health and life science students are used throughout. Selected solutions at end of text.
