This updated and enhanced Seventh Edition of CHEMISTRY IN FOCUS helps students develop an appreciation for the molecular world that underlies the world we can see. From the first page to the last, Professor Tro emphasizes the connection between the atoms and molecules that compose matter and the properties of that matter. Students learn to see the world through the lens of chemistry and to find excitement and awe in the myriad of chemical processes occurring all around them all the time. This easy-to-understand text also helps students understand the major scientific, technological and environmental issues affecting our society. Innovative study aids such as Self-Check Questions, OWLv2 Adaptive Study Plans and new online “Big Picture” videos featuring the author help students maximize their success in the course.

This updated and enhanced Seventh Edition of CHEMISTRY IN FOCUS helps students develop an appreciation for the molecular world that underlies the world we can see. From the first page to the last, Professor Tro emphasizes the connection between the atoms and molecules that compose matter and the properties of that matter. Students learn to see the world through the lens of chemistry and to find excitement and awe in the myriad of chemical processes occurring all around them all the time. This easy-to-understand text also helps students understand the major scientific, technological and environmental issues affecting our society. Innovative study aids such as Self-Check Questions, OWLv2 Adaptive Study Plans and new online “Big Picture” videos featuring the author help students maximize their success in the course. Updated Data. To ensure maximum relevance, all of the data relevant to today’s environmental and technological issues, such as Earth’s temperature, atmospheric carbon dioxide concentrations, rain acidity and pollution levels, have been thoroughly researched and made as current as possible. Updated Interest Boxes. Molecular Thinking, Molecular Focus, Molecular Revolution, and “What If” boxes have been updated to reflect progress and current issues. Revised Self-Check Questions. Every time a new concept is introduced, a multiple-choice Self-Check question gives students an opportunity to assess their understanding of that concept. To enhance student learning, self-check questions are now available in a digital environment that automatically tells students whether or not they answered correctly. A New Set of Instructional and Interactive Videos. These BIG PICTURE VIDEOS, featuring Professor Tro and created specifically for this new edition, can be assigned to students outside of class to introduce important topics in each chapter. Each video encourages active learning by stopping in the middle to ask students to answer a question. Two-part Visuals to Illustrate Thought Experiments. To help students make the connection between what they see and what is actually happening with atoms and molecules, the book includes innovative two-part visuals. One part is a macroscopic view of a familiar experience. The second part shows the microscopic image as a magnification window that portrays the molecular structure or reaction. "Molecular Thinking" Boxes. These boxes describe everyday observations related to chapter material and ask students to explain the observation based on what the molecules are doing. "Molecular Focus" Boxes. These boxes highlight a molecule relevant to the chapter, describing physical properties, structure, and uses of such compounds as calcium carbonate, hydrogen peroxide, ammonia, AZT, retinal, sulfur oxide, ammonium nitrate, and others. "Molecular Revolution" Boxes. Designed to encourage further exploration, these boxes describe a timely topic of modern research. "What If?" Boxes. These fascinating boxes focus on topics with societal, political, or ethical implications and conclude with open-ended questions for group discussion.
