This title is a Pearson Global Edition. The Editorial team at Pearson has worked closely with educators around the world to include content which is especially relevant to students outside the United States. Builds Twenty-First Century Skills NEW! 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.A new section (Section 1.4) introduces these skills and emphasizes their importance in student success. Enables deep conceptual understanding NEW! 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.Key Learning Outcomes correlate to the Chemical Skills and Examples in the end-of-chapter material and to the content within Mastering Chemistry. Each section in every chapter (after the introductory sections) includes at least one learning outcome summarizing the key learning objective to help students focus and assess their progress.Self-Assessment Quizzes at the end of each chapter provide opportunities for students to assess what they’ve learned. Each quiz consists of 10—15 multiple-choice questions similar to those found on standard exams.Multipart molecular images depicted through Macroscopic, Microscopic, and Symbolic perspectives enable students to better visualize, and thus understand, chemistry. Multipart images help students to see the relationships among 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).Abundant molecular-level views reveal the connections between everyday processes visible to the eye and the activities of atoms and molecules.Extensive labels and annotations for each illustration direct students to key elements in the art and help them to fully understand the processes depicted.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. Fosters development of problem-solving skills NEW! 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.In the ‘Strategize’ step for many examples, students are prompted to draw a solution map for the problem. Students learn how to use conversion factors and equations to outline the steps needed to get from the given to the unknown.Examples are presented in formats that foster problem-solving skills and enable understanding. All but the simplest examples are presented in a two-column format. The left column acts as the instructor’s voice, explaining the purpose of each step, while the right column shows how the step is executed. This format

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. MasteringTM Chemistry not included. Students, if Mastering Chemistry is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN and course ID. Mastering Chemistry should only be purchased when required by an instructor. Instructors, contact your Pearson rep for more information. Mastering Chemistry is the leading online homework, tutorial, and assessment system, designed to improve results by engaging students with powerful content. Instructors ensure students arrive ready to learn by assigning educationally effective content and encourage critical thinking and retention with in-class resources such as Learning CatalyticsTM. The Chemistry Primer helps students remediate their chemistry math skills and prepare for their first college chemistry course. Pre-built Assignments get students up to speed at the beginning of the course.Math is c
