The Eleventh Edition of Zumdahl/Zumdahl/DeCoste's CHEMISTRY continues its highly regarded tradition of emphasizing conceptual learning, critical-thinking and creative problem-solving techniques. An emphasis on modeling and interactive examples helps students learn to approach and solve chemical problems effectively--to think like chemists--so they can apply step-by-step problem-solving strategies not only to the text's diverse problems and exercises, but also to other aspects of their lives. The authors' engaging writing style makes even difficult material more engaging, and a proven learning approach helps students gain the knowledge and skills they need to become critical thinkers: to ask questions, to apply rules and models and to evaluate the outcome.
