Known for its carefully developed, thoroughly integrated approach to problem solving, this market-leading text emphasizes the conceptual understanding and visualization skills essential for first-year chemistry and science majors. The new technology program reinforces the approach of the text and provides a complete solution for teaching and learning.The Eighth Edition retains the hallmark pedagogical features of the text and builds upon the conceptual focus. In addition, figures and interactive animations in the updated art program help students connect molecular-level activity to macroscale phenomena. Students also benefit from online homework in the technology program, which features an extensive database of questions drawn from the text. Integrated course management tools allow instructors to customize presentation materials and test questions.New! Enhanced support of students' conceptual understanding includes Answer Check sections at the end of many worked-out examples; additional Concept Checks and Conceptual Problems, many with art; and more than 150 conceptual problems in the print and computerized Test Banks, many with graphics, for use in quizzes and tests.New! Chapters and appendices on thermodynamic data have been expanded and updated to include the recent values in the 1998 NIST-JANAF tables.In order to reinforce major chemical concepts, the authors present a proven six-part approach to problem solving that includes Example, Problem Strategy, Solution, Answer Check, Exercise, and corresponding End-of-Chapter Problems, many of which are presented in matched pairs.Coverage of cutting-edge issues in science and technology, as well as instrumental methods used in modern chemistry research, includes clear explanations and engaging examples in the boxed programs A Chemist Looks At and Instrumental Methods.
