This introductory text has been revised and updated to include a number of features that strengthen its emphasis on visualization, problem-solving and applications. All elements of the package - the text, CD-ROM, Web site and other supplements - work together to help students see the connections between the visible and molecular world, and understand how chemical knowledge is used to solve problems affecting all aspects of human life. The Student CD-ROM, developed with Sumanas, and CADRE (Roy Tasker, University of Sydney Nepean) is packaged with each copy of the text. It contains a number of features, including updated and expanded animations and simulations: Atomic Orbitals and Equilibrium, Stoichiometry, Ions in Solutions and Gas Law. Other electronic features include: nomenclature exercises; textbook animations; Q&A chapter self-quizzes; videos; a molecule database using Molecular Simulations Inc. (MSI) WebLab Viewer TM; Periodic Table visual database; curve fitter; plotter; and six calculators. There is also an on-line companion which, for students serves as as an electronic chapter-by-chapter study guide, with: chapter objectives; flash card exercises; interactive exercises and chapter self-quizzes; and four intensive practice tests.
