This title is a Pearson Global Edition. TheEditorial team at Pearson has worked closely with educators around the world toinclude content which is especially relevant to students outside the UnitedStates.

Chemistry: The Central Science, 15thEditionuses relevant content to engage students throughout the learningprocess, building skills that allow them to go beyond recall to effectivelysolve problems and visualize the atomic nature of the chemistry.

• Beyond Knowledge Recall:
• Integrative Exercisesconnect concepts in the current chapter with those from previous chapters and serve as an overall review of key concepts, helping students gain a deeper understanding of how chemistry fits together. Sample Integrative Exercises in many chapters show how to analyze and solve problems encompassing more than one concept.
• Design An Experiment activitiesprovide a departure from the usual end-of-chapter exercises with an inquiry-based, open-ended approach that stimulates a student to “think like a scientist.” Designed to foster critical thinking, each exercise presents the student with a scenario in which various unknowns require investigation. The student is called upon to ponder how experiments might be set up to provide answers to particular questions about observations.

• Relevance:
• A Closer Lookessays and features cover high-interest topics and have been updated to reflect recent news and discoveries in the field of chemistry, providing relevance and applications for students. End-of-chapter questions often give students the chance to test whether they understood the concept or not.
• Chemistry and Life and Chemistry Put to Workhelp students connect chemistry to world events, scientific discoveries, and medical breakthroughs.
• Problem Solving:
• How Tofeatures offer step-by step guidance for solving specific types of problems such as Drawing Lewis Structures, Balancing Redox Equations, Naming Acids, etc. These features, with numbered steps wrapped by a thin rule, are integrated into the main discussion and are easy to find.
• Aconsistent problem-solving processincorporated throughout guides students in practicing problem solving.
• The uniqueAnalyze–Plan–Solve–Check featurehelps students to understand what they are being asked as they solve, plan how to solve it, work their way through the solution, and check their answers.
• Selected sample exercisesuse a dual-column problem-solving strategy approach to show students the thought process involved in each step of a mathematical calculation.
• Data-Driven Problem Revisionswere made in an informed manner with the author team consulting the reservoir of data available through Pearson Mastering Chemistry to revise the question bank. This data enabled them to analyze which problems were frequently assigned and why; to pay careful attention to the amount of time it took students to work through a problem (flagging those that took longer than expected); and to observe the wrong answer submissions and hints used (a measure used to calculate the difficulty of problems). This “metadata” served as a starting point for the discussion of which end of chapter questions to modify, replace, or delete, resulting in a more diverse and polished set of problems.
• Streamlined End-of-Chapter and End-of-Section Exercisesare grouped by topic.
• Practice Exercisesprovide students with an additional problem to test mastery of the concepts in the text and to address the most common conceptual misunderstandings. To ensure that the questions touched on the most common misconceptions, the authors consulted the ACS Chemistry Concept inventory before writing their questions.Practice Exercisesaccompany each Sample Exercise within the chapters with correct answers provided in an appendix. Specific wrong answer feedback, written by the authors, will be available in Pearson Mastering Chemistry.
• Strategies for Successessays encourage students to think like chemists and aid students in analyzing information and organizing thoughts as a means to improve problem solving and critical thinking.
• Visualization:
• Visualizing Conceptsexercises precede the end-of-chapter exercises and ask students to consider concepts through the use of models, graphs, and other visual materials. These help students develop a conceptual understanding of the key ideas in the chapter. Additional conceptual exercises are found among the end-of-chapter exercises.
• Molecular illustrationshelp students see what is happening on a molecular level in the sample exercises
• Multi-Focus Graphicsprovide a variety of perspectives including macroscopic, microscopic, and symbolic to portray various chemical concepts. Students develop a more complete understanding of the topic being presented. Computer-generated molecular illustrations provide visual representations of matter at the atomic level.
• Go Figurequestions let students stop and take time to analyze the artwork in the text to be sure they understand the concept behind it.
• ENHANCED! Artcreates clarity and provides a cleaner more modern look with details that include white-background annotation boxes with crisp, thin leaders plus richer and more saturated colors in the art, and expanded use of 3D renderings.
• Annotationsoffer more detailed explanations; new leaders emphasize key relationships and key points in figures.
• Before/after photosnow more clearly show characteristics of endothermic and exothermic reactions. Added reaction equations connect the chemistry to what's happening in the photos.
