Long known for its focus on step-by-step skill building, Ebbing/Gammon/Koenigsmann/Wu's GENERAL CHEMISTRY, 12th Edition, has been thoroughly updated. Redesigned in-text worked examples and solutions offer a new scaffolded approach to help students develop problem-solving skills through a new "given, goal, guidance, reflection" framework. Updates throughout the text reflect the concerns of modern chemists with new coverage of materials in chemistry, nanotechnology, renewable energy, biochemistry and more. New biographical highlights of historical chemists from a variety of cultural backgrounds help students learn more about the diversity of scientists. Powered by Cengage's WebAssign platform, easily customizable homework assignments help students master core concepts and understand their mistakes.
