Career Focus Engages Students New and Updated - Chapter-opening Clinical Career focus provide engaging stories relating how chemistry is used daily in contemporary health-related professions and introduce the chemical concepts in each chapter. The chapter openers are now more clinically oriented with each story revisited with a Clinical Update at the end of chapter. New - Clinical Updates appears in the end-of-chapter material for each chapter and revisits the story from the Chapter-opening Career focus in the context of the chemistry learned in the chapter. Clinical Updates describe the follow-up treatment and provide additional application problems. Icons throughout the text highlight Clinical Update problems and provide examples of how allied health professionals use chemistry daily in their careers. New - Clinical Applications added to Practice Problems show the relevance between the chemistry content and medicine and health. Chemistry Links to Health and Environment throughout the text relate chemistry concepts to real-life topics in health, the environment, and medicine that interest students. Updated - Practice Problems, Sample Problems, and art demonstrate the connection between the chemistry being discussed and how these skills will be needed in professional experience. Builds Students’ Critical-Thinking and Problem-Solving Skills New - Review topics appear in the margin at the beginning of a Section, listing the Key Math Skills and Core Chemistry Skills from the previous chapters. New - Engage feature in the margin asks students to think about the paragraph they are reading and to test their understanding by answering the Engage question. New - Strategies for Learning Chemistry describe successful ways to study and learn chemistry. New - Expanded Study Checks in Sample Problems now contain multiple questions to give students additional self-testing practice. Updated - Concept Maps reflect the text’s new design. A Concept Map at the end of each chapter shows how all the key concepts fit together, encouraging learning with a visual guide to the interrelationship among all the concepts in each chapter. New - Try It First features have been added to each Sample Problem between the Question and the Solution. They remind students that the effort of attempting to solve a problem before looking at a solution helps to connect to newly learned ideas, practice retrieval of information, identify gaps in understanding, identify how ideas are related, and show them how to change their approach to the problem in the future. Updated - 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. New - Connect feature added to Analyze the Problem boxes indicates the relationships between Given and Need. Updated - Combining Ideas features offer sets of integrated problems that test students’ understanding and develop critical thinking by integrating topics from two or more previous chapters. New - The STEPs in the Sample Problems include a worked-out Solution plan for solving the problem. New - TEST feature added in the margin encourages students to solve related Practice Problems to practice retrieval of content for exams. Expanded - Analyze the Problem features are included in the solutions to the Sample Problems to strengthen critical-thinking skills and to help students break down word problems into the components required to s
