With an expanded focus on critical thinking and problem solving, the new Seventh Edition of Introductory Chemistry: Concepts and Critical Thinking prepares students for success in Introductory Chemistry courses. Unlike other introductory chemistry texts, all materials –the textbook, student solutions manual, laboratory manual, instructor’s manual and test item file – are written by the author and tightly integrated to work together most effectively. Math and problem solving are covered early in the text; Corwin builds student confidence and ability through innovative pedagogy and technology formulated to meet the needs of today’s learners. By presenting chemistry in a clear and interesting way, students to leave their first chemistry course with a positive impression, a set of new skills, and the desire to learn more.
- Chemistry is presented in a clear and interesting way, encouraging students to leave their first chemistry course with a positive impression, new skills, and the desire to learn more.
- Flexible chapter construction enables a seamless presentation of alternate sequences. For example, the interlude labeled Prerequisite Science Skills can be integrated into the instructor’s syllabus to ensure their students have the foundational knowledge to be successful in the course.
- Concept Exercises accompany all example and practice exercises, presenting each topic at a higher level.
- Critical thinking vignettes feature such diverse topics as nuclear medicine, bottled water and neon lights — and self-tests at the end of each chapter help students hone their critical thinking skills.
- Strategy Plans and Unit Analysis Maps, in selected example exercises in the quantitative chapters reinforce steps 1, 2, and 3 for every calculation, give students a method they can use when solving certain types of problems:
Step 1: The unit asked for in the answer.
Step 2: The relevant given value.
Step 3: The unit conversion factor(s).
- Using the unit analysis method, Two-Column Example Exercises show students a logical way to apply the three-step problem solving access in some of the worked-out example problems.
- Comprehensive problem-solving support includes visual problem-solving strategies, problem-solving organizers and a plethora of exercises to help students improve their problem-solving skills in a variety of ways to ease the experience of learning chemistry.
- Problem Solving Organizers are found at the end of certain chapters dealing with calculations. In the first column is a synopsis of the types of calculations in the chapter. In the second column is the correct procedure for solving each type of problem covered in the chapter. In the third column is an illustrated example of the problem type.
- The format of the Example Exercises demonstrates concepts and critical thinking: Example Exercise, Solution, Practice Exercise, Concept Exercise.
- Key Concepts help students identify the core concepts of chemistry and guide their conceptual understanding of these topics.
- Macro/Micro and molecular art helps students connect the things they encounter in everyday life (the macro view) with depictions of molecules that chemists visualize every day (the micro view). In Corwin's text, the two representations are presented together.
- Atomic/molecular graphics demonstrate macroscopic/molecular relationships, and help students connect the seen and unseen world of chemistry.
- 'Chemistry Connections' are vignettes that cover industrial processes, consumer chemistry, historical profiles, environmental concerns, and more. They familiarize students with motivational, real-world applications that emphasize the important role of chemistry in everyday life.
- Online exercises at the end of chapter provide web-based collaborative activities to help students develop critical thinking skills.
New to this Edition
- Expanded Chapter Openers now include an “Elements and the Environment” feature with photos and descriptions of elements that play a prominent role in the environment.
- Streamlined single-section coverage of scientific measurements (contains parts of former Ch. 2) focuses on seven prerequisite math skills:
- PSS.1 Measurements
- PSS.2 Significant Digits
- PSS.3 Rounding Off Nonsignificant Digits
- PSS.4 Adding and Subtracting Measurements
- PSS.5 Multiplying and Dividing Measurements
- PSS.6 Exponential Numbers
- PSS.7 Scientific Notation
- Learning Objectives table at the end of each chapter correlated to sections and the end of chapter exercises for a greater connection between concepts and problems.
- New Ch. 15 (Advanced Problem Solving) provides a comprehensive treatment of problem solving, including chemical formula and equation calculations, multiple-reaction stoichiometry, and advanced problem-solving examples and strategies.
- The text’s discussion of scientific notation and significant digits now appears in an Appendix.
- Updated and expanded end-of-chapter material includes new Challenging Exercises and web-based collaborative activities, titled Online Exercises, to help students develop both critical thinking and interpersonal skills.
- Updated Chemistry Connections demonstrate how chemistry is part of our day-to-day activities and real-world events. Topics range from the Olympics and nanotechnology to Avogadro’s Number.
- Updated Self-Tests conclude each chapter with Review Exercises (multiple-choice), Key Concepts questions (short answer), and Critical Thinking questions (short answer).
