This package includes a physical copy of Principles of Chemistry: A Molecular Approach: International Edition, 2/e by Nivaldo Tro, as well as access to the eText and MasteringChemistry. Adapted from Nivaldo J. Tro's best-selling general chemistry book, Principles of Chemistry: A Molecular Approach focuses exclusively on the core concepts of general chemistry without sacrificing depth or relevance. Tro's unprecedented two- and three-column problem-solving approach is used throughout to give students sufficient practice in this fundamental skill. A unique integration of macroscopic, molecular, and symbolic illustrations helps students to visualize the various dimensions of chemistry; Tro's engaging writing style captures student's attention with relevant applications. The Second Edition offers a wealth of new and revised problems, approximately 50 new conceptual connections, an updated art program throughout, and is available with MasteringChemistry(R), the most advanced online tutorial and assessment program available. MyLab and Mastering from Pearson improve results for students and educators. Used by over ten million students, they effectively engage learners at every stage. With proven success, Mastering has helped students make strides in learning for over 10 years. MasteringChemistry has immersive content and tools that are so engaging that Ann Verner, at the University of Toronto Scarborough, Canada, said, "MasteringChemistry is the best online chemistry homework program that I have used. The structure of the questions and the hints motivate the students to continue working on the problems, and the immediate feedback increases their confidence." With MasteringChemistry, students gain knowledge that they will use throughout their lives, and universities gain a partner deeply committed to helping students and educators achieve their goals. For students Pearson eText gives you access to an eBook that can be used on the go, and allows you to highlight, search and take notes as you read online. Access to the eBook depends on the package you have bought. You can work through the problems at your own pace, opening hints if you need help. If you make an error, you are given feedback based on that specific mistake so you can learn from it. PhET simulations let you to get hands on to understand how the theory and daily life link up. These fun, interactive, research-based simulations of physical phenomena come from the PhET project at the University of Colorado. For educators Online assignments, tests, quizzes can be easily created and assigned to students. Gradebook: Assignments are automatically graded and visible at a glance.
