Principles of Chemistry:A Molecular Approach: International Edition

Description

Features

• A streamlined, brief text that covers all the necessary topics required for a one- or two-semester general chemistry course, for the professor who wants a book that only covers the topics they need. At only 20 chapters, this text has no separate nonmetals, metals or coordination compounds chapters.
• Tro's engaging writing style entices the reader into the chemistry by discussing a relevant, real-life example first. He then weaves in the chemistry into relevant examples and problems thus providing a context for greater understanding and comprehension.
• Annotated molecular art and multipart images help students see the relationship between the formulas they write down on paper (symbolic), the world they see around them (macroscopic), and the atoms and molecules that compose that world (molecular).
• Two- and three-column problem solving examples help students understand the logic and purpose of each step in the problem-solving process.
  • Tro acts as the voice of the professor by providing the written explanation of how to solve the problem in the left-hand column.
  • In the right-hand column, Tro solves in parallel the problem as it was just described in the left-hand column. This simulates the in-class experience when a professor works a problem on the board and explains each step along the way.
  • Tro's procedure maps not only work out a problem for students, but also apply the same methodology to another problem side by side.
• MasteringChemistry®. MasteringChemistry from Pearson has been designed and refined with a single purpose in mind: to help educators create that moment of understanding with their students. The Mastering platform delivers engaging, dynamic learning opportunities-focused on your course objectives and responsive to each student's progress-that are proven to help students absorb course material and understand difficult concepts. By complementing your teaching with our engaging technology and content, you can be confident your students will arrive at that moment-the moment of true understanding. http://www.masteringchemistry.com.
  • The MasteringChemistry tutorial system helps students figure out where they are going wrong when problem solving by providing answer-specific feedback and coaching. By offering feedback specific to wrong answers given, MasteringChemistry tutorials coach 92% of students to the correct answer.
  • The program enables professors to compare their class performance against the national average on specific questions or topics. At a glance, professors can see class distribution of grades, time spent, most difficult problems, most difficult steps and even the most common answer.
  • Pearson eText gives students access to the text whenever and wherever they can access the Internet. The eText pages look exactly like the printed text, and include powerful interactive and customization functions. This does not include the actual bound book.

New to this Edition

• NEW! Approximately 50 new Conceptual Connections have been added, including a selection that involves visualization and drawing. These are strategically placed to help students check their conceptual understanding of the most complex concepts. As a result, the book now has over 50% more Conceptual Connections than the previous edition, and the majority of these will also be available to assign in MasteringChemistry.
• NEW! Approximately 150 new end-of-chapter problems are included, particularly in the cumulative and challenge categories. All end-of-chapter problems have been examined and revised where necessary for clarity and concision, using statistical analysis of data culled from MasteringChemistry where possible.
• NEW! A new design and revised art program helps to increase readability, clarity, and visual appeal. Figures and Figure captions were examined and revised as needed to improve teaching focus. Two- and three-column in-text examples are easier to navigate and work through based on design modifications such as:
  • Highlighting the Example number, making it easy for students to recognize they have reached a worked example.
  • Tinting the "For Practice" problems so students can see at a glance the problems that have been included for them, to test their mastery of the concept being taught in the worked example.
  • In two-column examples, the steps outlined by the author (Sort, Strategize, Solve and Check) as well as the steps showing how each is executed (Given, Conceptual Plan, Relationships Used, and Solution) are now boldfaced for easier reference.
• Revised coverage of Thermochemistry (Chapter 6) with a focus on making content more accessible and relevant for students, based on the results of reviewer and focus group feedback.
  • The chapter 6 opener has been revised from a discussion on furnaces to a explanation of how the principles of thermochemistry are involved in hand warmers often used by snowboarders and skiers.
  • Section 6.2, The Nature of Energy: Key Definitions is a new division in the chapter and content in the Internal Energy discussion has been rewritten for better clarity.
  • In addition, a new subsection on Thermal Energy Transfer has been added to Section 6.4 (Quantifying Heat and Work) that contains a more in depth description on the topic, as well as a new figure, conceptual connection, and worked example.
• A revised Chapter 7 (The Quantum-Mechanical Model of the Atom):
  • Features an updated chapter opener that is more student-friendly and relevant than the previous edition.
  • Weaves the chapter opener discussion throughout the chapter. The discussion of The Uncertainty Principle in Section 7.4 (The Wave Nature of Matter: The De Broglie Wavelength, the Uncertainty Principle, and Indeterminacy) has been revised and linked to the material in the new Section 7.1.
  • Now includes the introduction of spin quantum number (formerly found in Chapter 8).
  • Expands and clarifies the description of photoelectric effect in Section 7.e, The Nature of Light, and now includes a new graph of kinetic energy versus wavelength for the photoelectric effect to help with student comprehension of this topic.
• An extensively revised explanation of entropy in chapter 17 includes a new section in 17.3 that better describes the concepts of microstates and macrostates, along with two new figures that help lay the foundation for a better understanding of entropy.
• NEW! New worked examples have been added to chapter 3 (balancing chemical equations that contain polyatomic ions), chapter 6 (thermal energy transfer) and chapter 12 (calculating the vapor pressure of a solution containing an ionic solute).
• Data has been updated throughout the text based on current events, such as Information about the Fukushima nuclear accident and the termination of the Yucca Mountain Nuclear Waste Repositiry (added to Section 19. 5, The Discovery of Fission: The Atomic Bomb and Nuclear Power.)
