دانلود کتاب Chemistry for Changing Times (12th Edition)

  Times are changing more rapidly than ever—particularly in the vital areas of biochemistry, the environment, energy, drugs, and health and nutrition. In this revision, the authors of Chemistry for Changing Times strengthen the book's environmental focus by tying “Environmental Explorations” exercises to the media, and by implementing a framework that uses the ACS’s Environmental Principles, which are written by experts in the field. This reference puts chemistry in an approachable context and personalizes it for today's readers, enabling them to focus on evaluating information about real-life issues rather than memorizing rigorous theory and mathematics. Four chapters (19 through 22) are now posted online; Hill/Kolb is going green by reducing page length overall and moving four chapters from the text to the Web. A new, robust ebook with rich media assetsincludes Whiteboard problem-solving videos for every worked example in the book; section-ending self assessment questions from the book; and Green Explorations critical-thinking exercises link text and media.
