Chemistry for Changing Times, 12th Edition

• The concept of “Green Chemistry” is incorporated throughout the text by implementing a framework using the ACS’s Environmental Principles written by experts in the field and tying in the Green Chemistry Essays at the end of each chapter.

• Green Chemistry Essays include topics that have been carefully chosen to introduce students to this concept—a new approach to designing chemicals and chemical transformations that are beneficial for human health and the environment.

• Critical Thinking Exercises encourage students to think critically and apply information from the chapter in both concrete and abstract ways.

• Conceptual Problem-Solving Examples guide students through the process of learning and understanding important chemical concepts.

• Collaborative Group Projects are end-of-chapter exercises that help professors engage students in collaborative work with group assignments.
 
• Chapter Summaries are organized by sections, with key terms highlighted, to remind students of important concepts.

• Molecular art features Illustrations using a two-part visual image: microscopic and macroscopic views help students visualize what is happening on a molecular level.

• Environment-focused applications include many interesting, relevant and environment topics to help student connect chemistry to the world around them.

• Both SI and the traditional English system for measurement have been incorporated within the text.
