Chemistry: An Introduction to General, Organic, and Biological Chemistry, Twelfth Edition is the ideal resource for today’s allied health students. Assuming no prior knowledge of chemistry, author Karen Timberlake engages students through her friendly presentation style and reveals connections between the structure and behavior of matter and its role in health and the environment. With a renewed focus on problem-solving skills, the Twelfth Edition encourages active learning through the new, interactive Pearson eText enhanced with media within Mastering Chemistry. New Interactive Videos, Sample Calculations, ‘Problem Solving in Allied Health’ Tutorials, and Dynamic Study Modules bring chemistry to life and walk students through different approaches to problem solving, providing remediation where needed.

This program provides a better teaching and learning experience–for you and your students. It will help you to:
• Personalize learning with Mastering Chemistry®: This online homework, tutorial, and assessment program helps students master core concepts and problem-solving skills, thus freeing up time in the classroom for instructors to focus on complex topics.
• Show the relevance of chemistry through real-world examples: Activities and applications throughout the program couple chemistry concepts with health and environmental career applications to help students understand why course content matters.
• Foster development of problem-solving skills: The program introduces a variety of clear problem-solving strategies early in the text that are reinforced through Allied Health Tutorials in Mastering Chemistry and revisited when needed.
• Help students visualize and understand concepts: The text’s engaging visual features, including macro-to-micro illustrations, a rich photographic program, and concept maps, help students understand chemistry by seeing chemistry.

PREFACE
Welcome to the twelfth edition of Chemistry:
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.
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 New for the Twelfth Edition This new edition introduces more problem-solving strategies, including new Key Math Skills; new Core Chemistry Skills; new Analyze the Problem features; more Guides to Problem Solving; and more conceptual, challenge, and combined problems. New and updated features have been added throughout this twelfth edition, including the following:
• NEW AND UPDATED! Chapter Openers provide modern examples and engaging stories that illustrate how the chemistry you will be learning in each chapter relates to allied health professional experience.
• NEW! Chapter Readiness sections at the beginning of each chapter list the Key Math Skills and Core Chemistry Skills from the previous chapters, which provide the foundation for new chemistry principles in the currentchapter.
• NEW! Key Math Skills review basic math relevant to the chemistry you are learning throughout the text. A Key Math Skill Review at the end of each chapter summarizes and gives additional examples.
• NEW! Core Chemistry Skills identify the key chemical principles in each chapter that are required for successfully learning chemistry. A Core Chemistry Skill Review at the end of each chapter helps reinforce the material and gives additional examples.
• Analyze the Problem features included in the solutions of the Sample Problems strengthen critical-thinking skills and illustrate the breakdown of a word problem into the components required to solve it.
• UPDATED! Questions and Problems, Sample Problems, and art are directly related to nursing and health applications to better demonstrate the connection between the chemistry being discussed and how these skills will be needed in professional experience.
• UPDATED! Combining Ideas features offer sets of integrated problems that test students’ understanding by integrating topics from two or more previous chapters.
• UPDATED! Chapter Reviews now include bulleted lists and thumbnail art samples related to the content of each section.
Chapter Organization of the Twelfth Edition
In each textbook I write, I consider it essential to relate every chemical concept to real-life issues of health and environment. 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, introduces the concepts of chemicals and chemistry, discusses the scientific method in everyday terms, guides students in developing a study plan for learning chemistry, and now has a new section of
Key Math Skills, which reviews basic math needed for learning chemistry. The section on Writing Numbers in Scientific Notation was moved from Chapter 2 and is now part of the section
of Key Math Skills in this chapter.
• A new chapter opener features the work and career of a forensic scientist.
• A new section, “Scientific Method: Thinking like a Scientist,” has been added, which discusses the scientific method in everyday terms.
• A new section, “Key Math Skills for Chemistry,” reviews basic math required in chemistry, such as Identifying Place Values 11.4A2, Using Positive and Negative Numbers in Calculations 11.4B2 including a new feature Calculator Operations, Calculating a Percentage 11.4C2, Solving Equations 11.4D2, Interpreting a Graph 11.4E2, and Writing Numbers in Scientific Notation 11.4 F2.
New sample problems with nursing applications are added. New Sample Problem 1.1 illustrates the use of scientific method in the nursing environment, and new Sample Problem 1.4 requires the interpretation of a graph to determine the decrease in a child’s temperature when given Tylenol.
• New art includes a photo of a nurse making observations 1scientific method2 in the hospital, and a plastic strip thermometer placed on a baby’s forehead to determine body temperature.
Chapter 2, Chemistry and Measurements, looks at measurement and emphasizes the need to understand numerical relationships of the metric system. Significant numbers 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.
• A new chapter opener features the work and career of a registered nurse.
• New material is added that illustrates how to count significant figures in equalities and in conversion factors used in a problem setup.
• New abbreviation mcg for microgram is introduced as used in health and medicine.
