The most successful first edition General Chemistry text published in the last decade, CHEMISTRY: THE MOLECULAR SCIENCE continues in this new edition to emphasize the traditional core concepts covered in the general chemistry course. Lauded for its focus on visualization for understanding in support of students' conceptual development and its dedicated emphasis on content mastery through a proven problem-solving methodology that actively engages students in the chemical thought process, this Second Edition offers a complete pedagogical solution. The text's student focus is extended through General ChemistryNow--the first assessment-centered Web-based learning tool for general chemistry. Developed in concert, the unparalleled integration of text and media provides students with a seamless learning system. Based on extensive user and reviewer feedback, the Second Edition has been significantly revised to meet the content and organizational needs of today's general chemistry classroom. CHEMISTRY: THE MOLECULAR SCIENCE is intended for mainstream general chemistry courses geared toward students who expect to pursue further study in science, engineering, or science-related disciplines.
- NEW!-The Second Edition features unparalleled text/media integration with General ChemistryNow (http://chemistry.brookscole.com/moore2e). This Web-based assessment-centered learning tool was developed in concert with the text. Throughout each chapter, icons with captions alert students to resources--quizzes, simulations, "Active Figures," and "Coached Problems"--that enhance problem-solving skills and improve conceptual understanding. In General ChemistryNow, students are provided with a Personalized Learning Plan--based on a diagnostic Pre-Test--that targets their study needs and helps them to visualize, practice, and master the material in the text. PIN code access to General ChemistryNow is packaged FREE with every new copy of the text.
- Throughout the text, familiarity with the three conceptual levels of chemistry is emphasized: Macroscopic (laboratory or real-world phenomena), Nanoscale (particles: atoms, molecules, and ions), and Symbolic (chemical formulas and equations).
- A proven problem-solving methodology is introduced in Chapter 1 and utilized throughout the book. Each chapter contains many worked-out "Problem-Solving Examples"--a total of 260 in the book as a whole. Most consist of five parts: a Question (problem); an Answer, stated briefly; a Strategy and Explanation section that outlines one approach to solving the problem and provides significant help for students whose answer did not agree with the proposed approach; a Reasonable Answer Check section marked with an icon that indicates how a student could check whether a result is reasonable; and a Problem-Solving Practice that provides a similar question or questions, with answers appearing only in an appendix.
- To further ensure that students do not merely memorize algorithmic solutions to specific problems, 339 exercises are provided, which appear immediately following new concepts as they are introduced.
- Enhancing students' abilities to estimate results is the goal of the "Estimation" boxes found in many chapters. Each "Estimation" poses a problem that relates to the content of the chapter in which it appears and for which a rough calculation suffices. Students gain knowledge of various means of approximation, such as back-of-the-envelope calculations and graphing, and diverse sources of information, such as encyclopedias, handbooks, and the Internet.
- "Examples," "Practice Problems," "Estimation" boxes, and "Exercises" are all intended to stimulate active thinking and participation by students as they read the text and to help them hone their understanding of concepts. The grand total of these active-learning items--599 strong--exceeds the number found in any similar textbook.
- Recipient of the coveted Talbot award for visual excellence, the text continues to engage today's visually oriented students. Illustrations are designed to help students visualize atoms and molecules and to make connections among macroscale observations, nanoscale models and symbolic representations of chemistry. Visualization for understanding is emphasized throughout, resulting in an exceptionally effective way for students to learn how chemists think about the nanoscale world of atoms, molecules, and ions. Many kinds of visualization, including the use of text balloons, are used in support of students' conceptual development.
- "Interdisciplinary Applications" (including environmental and industrial chemistry applications) have been included, especially those applications that students will revisit when they study other natural science and engineering disciplines. Applications have been integrated where they are relevant, rather than being relegated to isolated chapters and separated from the principles and facts on which they are based. Students in a variety of disciplines will discover that chemistry is fundamental to their other studies.
- The authors have especially emphasized the integration of organic chemistry and biochemistry throughout the book. In many areas, such as stoichiometry and molecular formulas, organic compounds provide excellent examples. Many of the principles that students encounter in general chemistry are directly applicable to biochemistry, and a large percentage of the students in most general chemistry courses are planning careers in biological or medical areas that make constant use of biochemistry. For this reason, the authors have chosen to deal with fundamental biochemical topics in juxtaposition with the general chemistry principles that underlie them.
- NEW!-End-of-chapter problem sets include "More Challenging Problems" as well as an increased number of conceptual problems, ensuring that students have ample opportunity to test their mastery of chapter concepts at a variety of skill levels. Selected end-of-chapter problems are also available through OWL (Online Web-based Learning System).
- NEW!-Every "Problem-Solving Example" in this Second Edition now includes an additional "Strategy and Explanation" section to help students understand and model through explicit explanation the clear strategy/approach chosen to solve each problem. Additionally, 24 new Problem-Solving Examples and 39 new Exercises have been added.
- NEW!-Integrated throughout the text, new "Focus On" figures enhance and visually reinforce students' understanding of abstract concepts. "Focus On" figures allow students to use a visual image as a building block to understanding. These key illustrations from the text have been animated online and are accessible at the General ChemistryNow Web site. To ensure understanding of the concept played out in the "Focus On" animation, each active figure is accompanied by a set of corresponding tutorials.
- NEW!-The Second Edition features significantly revised and expanded coverage of descriptive chemistry. Chapter 21, "The Chemistry of the Main Group Elements," now includes an extensive discussion of the periodic properties of the main group elements and Chapter 22, "Chemistry of Selected Transition Elements and Coordination Compounds," now includes new material on crystal-field theory and colors of coordination compounds.
- NEW!-"Significant Figures," formerly Appendix A.3, is now featured in Chapter 2, "Atoms and Elements," to help students gain a more complete understanding of the topic. "Molecular Orbital Theory," formerly Appendix D, is now discussed in Chapter 8, "Covalent Bonding," with clarified and enhanced coverage of ionic bonding.
- NEW!-Coverage of intermolecular forces has been expanded to include a discussion of Coulomb's Law in Chapter 8, "Molecular Structures," and Chapter 11, "Liquids, Solids, and Materials," now includes new material on vapor pressure and the Clausius-Clapeyron equation.
- NEW!-The authors have also enhanced popular, pedagogically sound features such as "Chemistry in the News" (feature boxes that bring the latest discoveries in chemistry and applications of chemistry to students' attention), "Chemistry You Can Do" (experiments that use household chemicals and equipment to emphasize the real world connections of chemistry), "Portrait of a Scientist," and "Tools of Chemistry" (boxes that provide examples of how chemists use modern instrumentation to solve challenging problems). Most of these features have been updated and many are entirely new.
- NEW!-The authors have made use of recently published pedagogical research that points the way toward teaching methods and writing characteristics that are most effective in helping students learn chemistry and retain their knowledge over the long term. For example, the convention for calculating the potential of an electrochemical cell in Chapter 19 has been modified in light of recent research published in the "Journal of Chemical Education," and the already excellent treatment of entropy in Chapters 14 and 18 has been rewritten to make it clear that entropy measures dispersal of energy.
