Building on the strengths that have made Karen Timberlake a best-selling author in the one-semester allied health market, General, Organic, and Biological Chemistry: Structures of Life, Second Edition now offers even more quantitative and conceptual coverage and the most comprehensive media package available. General, Organic, and Biological Chemistry: Structures of Life also provides all of Timberlake's proven pedagogical features: a clear and friendly writing style, a student-focused approach, and real-world, health-related applications that students can relate to. Designed primarily for the two-semester GOB course (but also suitable for one-semester courses looking for a comprehensive approach), the Second Edition develops students' conceptual skills with new Concept Maps throughout the book that summarize and tie together chapter topics. Chemical concepts are broken into bite-size pieces, with a step-by-step approach that provides clear and thorough understanding, and conceptual questions at the end of each chapter test student comprehension of the material. New problems have been added throughout the text and more quantitative coverage has been added to the general chemistry section. A new color-coded Guide to Problem Solving helps students master problem-solving skills. The book's new media package features MasteringChemistry®, the most effective online homework and tutorial system available. MasteringChemistry is automatically packaged with every new copy of the book. A clear writing style connects chemistry to the real world, addresses a variety of learning styles, and makes chemistry accessible to students with little or no background. Sample Problems with Study Checks appear throughout each section, giving students an opportunity for immediate practice. A step-by-step approachbreaks down problems into easy to follow steps. Questions and Problemsfollow every section for immediate reinforcement of concepts just discussed. Paired problemswithin a chapter and at the end of a chapter are highlighted with alternating colors. Health Notes apply chemical concepts to real-life issues and relevant topics in health and medicine. Environmental Notes cover issues such as global warming, radon, ozone depletion, and acid rain, tying chemistry to the real world. Career Focus chapter openers begin with interviews of people in different chemistry-related fields. The career connections continue in the examples in the text and problems, the Career Focus boxed feature, and on the web. The Career Focus feature makes relevant links between the students' chemistry course and their future career. Media icons in the margins direct students to tutorials and case studies on The ChemistryPlace® Website for General, Organic, and Biological Chemistry: Structures of Life, Second Edition. A media grid in front of the book correlates the media with the book.
