New problem-solving tools in this edition, including Try it First and Connect, urge readers to think critically about problem-solving while learning best practices.

PREFACE
Welcome to the thirteenth edition of An Introduction to General, Organic, and Biological Chemistry. This chemistry text was written and designed to help you prepare for a career in a health-related profession, such as nursing, dietetics, respiratory therapy, and environmental and agricultural science. This text assumes no prior knowledge of chemistry. My main objective in writing this text is to make the study of chemistry an engaging and a positive experience for you by relating the structure and behavior of matter to its role in health and the environment. This new edition introduces more problem-solving strategies, more problem-solving guides, new Analyze the Problem with Connect features, new Try It First and Engage features, conceptual and challenge problems, and new sets of combined problems.
It is my goal to help you become a critical thinker by understanding scientific concepts that will form a basis for making important decisions about issues concerning health and the environment. Thus, I have utilized materials that
• help you to learn and enjoy chemistry
• relate chemistry to careers that interest you
• develop problem-solving skills that lead to your success in chemistry
• promote learning and success in chemistry

Chapter Organization of the Thirteenth Edition
In each textbook I write, I consider it essential to relate every chemical concept to real-life issues. Because a chemistry course may be taught in different time frames, it may be difficult to cover all the chapters in this text. However, each chapter is a complete package, which allows some chapters to be skipped or the order of presentation to be changed.
Chapter 1, Chemistry in Our Lives, discusses the Scientific Method in everyday terms, guides students in developing a study plan for learning chemistry, with a section of Key Math Skills that reviews the basic math, including scientific notation, needed in chemistry calculations.
• The Chapter Opener tells the story of a murder and features the work and career of forensic scientists.
• A new Clinical Update feature describes the forensic evidence that helps to solve the murder and includes Clinical Applications.
• “Scientific Method: Thinking Like a Scientist” is expanded to include law and theory.
• Writing Numbers in Scientific Notation is now a new Section.
• An updated Section titled Studying and Learning Chemistry expands the discussion of strategies that improve learning and understanding of content.
• Key Math Skills are: Identifying Place Values, Using Positive and Negative Numbers in Calculations, Calculating Percentages, Solving Equations, Interpreting Graphs, and Writing Numbers in Scientific Notation.
Chapter 2, Chemistry and Measurements, looks at measurement and emphasizes the need to understand numerical relationships of the metric system. Significant figures are discussed in the determination of final answers. Prefixes from the metric system are used to write equalities and conversion factors for problem-solving strategies. Density is discussed and used as a conversion factor.
