●13 New Conceptual Checkpoint questions have been added throughout the book. Conceptual Checkpoints reinforce conceptual understanding of the most complex material. Strategically located throughout each chapter, they prompt students to think about concepts and solve problems without doing any math. Answers and explanations appear at the end of each chapter.
●REVISED! The art program has been further refined and improved, making the visual impact sharper and more targeted for student learning. The art program has been modified to move information from the captions and into the art itself. This allows relevant information to be placed right where it is most needed and makes the art a more accessible study and review tool.
●Data Interpretation and Analysis, a new category of end- of- chapter questions has been added to each chapter. These questions present actual data from real-life situations and ask students to analyze and interpret that data. They are designed to give students much- needed practice in reading graphs, understanding tables, and making data-driven decisions.
●39 Interactive Worked Examples instruct students how to break down problems using Tro’s “Sort, Strategize, Solve, and Check” technique in an interactive, digital format. These problems are incorporated in Mastering™ Chemistry as assignable activities and are embedded in eText 2.0
●UPDATED! The data throughout the book has been updated to reflect the most recent measurements and developments available.
For example, the half-life of Carbon-14 has been changed to 5715 years in Table 17.2 and throughout Chapter 17 to reflect the current accepted value and new information has been added about thermoluminescent dosimeters in Section 17.4.
Other updates include changes made to Figure 8.2 Climate Change, Section 10.1 Bonding Models and AIDS Drugs, Table 11.5 Changes in Pollutant Levels for Major U.S. Cities, 1980—2014, The Chemistry in the Environment box in Section 12.8 Water: A Remarkable Molecule, and Section 17.8 Nuclear Power: Using Fission to Generate Electricity.
●UPDATED! Several chapter-opening sections (and/or the corresponding art), including Sections 1.1, 2.1, 12.1, and 16.1, have been replaced or significantly modified.
●A new section (Section 2.8), new example (Example 2.12), and new end-of-chapter problems address conversions involving quantities with combined units, such as mL/kg or km/hr.
●Temporary symbols for elements 113, 115, 117, and 118 (Uut, Uup, Uus, and Uuo, respectively) have been added to all periodic tables.
●REVISED! Text in all chapters has been edited for clarity and to limit use of passive voice and extraneous words and phrases.
