The Eighth Edition of Zumdahl and DeCoste's best-selling BASIC CHEMISTRY, 8e combines enhanced problem-solving structure with substantial pedagogy to enable students to become strong independent problem solvers in the introductory course and beyond. Capturing student interest through early coverage of chemical reactions, accessible explanations and visualizations, and an emphasis on everyday applications, the authors explain chemical concepts by starting with the basics, using symbols or diagrams, and conclude by encouraging students to test their own understanding of the solution. This step-by-step approach has already helped hundreds of thousands of students master chemical concepts and develop problem-solving skills. The book is known for its focus on conceptual learning and for the way it motivates students by connecting chemical principles to real-life experiences in chapter-opening discussions and 'Chemistry in Focus' boxes (with many new ones added). Almost all of the in-text examples are now 'Interactive Examples' and available online. These computer-based examples throughout the text require students to think through the Example step-by-step rather than simply scan the written Example in the text as many students do. New 'Critical Thinking' boxes have been added. Many images have been significantly updated according to a new art style program to better serve visual learners. The Chapter Review section has been reorganized with a new structure along with a major revision to the review content. Key Terms have been updated throughout. A significant number of end-of-chapter questions have been added and revised. A new end-of-chapter question section titled 'ChemWork' has been added and students can work on these types of problems online.
