Revised to enhance course management opportunities for instructors--and to help students obtain a higher level of understanding of general chemistry concepts--CHEMISTRY & CHEMICAL REACTIVITY, 7e, International Edition, provides the most robust homework/assessment tools ever offered in chemistry. The new edition combines the text’s signature logical organization, macro to micro orientation, and superior art program with the most completely integrated technology package on the market. Every chapter has been scrutinized for clarity, level, and integration of media, which includes hundreds of guided simulations, animations, video clips, and a personal tutor. Online Web-based Learning, OWL, is a fully customizable Web-based homework system with an optional e-book that maximizes student study time--and your options for assignments. CengageNOW™ ™, a Web-based tutorial with e-book, generates a personalized learning plan to meet your students’ specific needs. Offering engaging detail, the text’s new art program is fully integrated with both online resources. Additional more challenging end-of-chapter Study Questions, which are fully assignable in OWL, give you more choices. Quality writing, seamless technology integration, and a rich ancillary package remain the hallmarks of CHEMISTRY & CHEMICAL REACTIVITY, 7e, International Edition.
New to this edition
Online Web-based Learning (OWL): Class-proven by thousands of students, OWL is a fully customizable and flexible Web-based homework system and assessment tool. With both numerical and chemical parameterization--and built-in response-specific feedback--OWL produces over 100,000 general chemistry questions correlated to the text. It includes a database of simulations, guided tutorials, and end-of-chapter Study Questions, as well as an optional e-book version of CHEMISTRY & CHEMICAL REACTIVITY, 7e, International Edition. Even more end-of-chapter questions from the seventh edition have been added to OWL.
New Chapter Organization: In response to users, the first few chapters of the book have been slimmed down and reorganized into four rather than five chapters. In addition, the chapter on intermolecular forces, liquids, and solids in the sixth edition has been organized into two chapters, which allows incorporation of ionic bonding and some materials chemistry in the new chapter on the solid state.
Moles of Reaction: The concept of moles of reaction is now introduced in a box in the stoichiometry chapter for those instructors who want to use the approach in solving stoichiometry problems. It is also integrated in the thermodynamics chapters in the units on thermodynamic quantities.
Case Studies: At appropriate places in each chapter are new Case Study boxes. These cases describe where chemistry has been used to solve a problem or where chemistry is important in everyday matters. Examples include the use of isotopes to catch athletes who cheat using illegal drugs, a washing machine that injects silver into the wash, acryalmide in French fries, a comparison of ethanol and gasoline, and the amount of salt in seawater. Questions are posed in each Case Study and are answered in an appendix.
"In the Laboratory" Questions: A new section of end-of-chapter questions addressing techniques used and work performed in the general chemistry laboratory has been introduced as appropriate to make the connection between lecture topics and lab work. For example, Chapter 4 (on stoichiometry) contains a new section on using spectrophotometry.
Features
CengageNOW™™: Integrated with the text, this online tool gives students the resources and responsibility to manage concept mastery in an efficient manner. CengageNOW™™ helps students assess their unique study needs by providing a personalized study plan. CengageNOW™™ offers over 400 step-by-step tutorial modules tied to end-of-chapter Study Questions. Students can access material in numerous ways to suit their learning styles. It includes an e-book.
Interchapters: Addressing topics in a brief but visually exciting way, insightful interchapters on biochemistry, modern materials, environmental chemistry, and the chemistry of energy sources have been revised for the seventh edition to include current information. This format allows these topics to be easily integrated into the course or skipped without interrupting the narrative. A new interchapter on the historical development of chemistry quest authored by noted chemistry author John Emsley has been added to the new edition.
Beyond the Exam: The text correlates Chapter Goals with Study Questions to help students go beyond "studying for the exam" to gain a true conceptual understanding of the concepts. Each chapter is introduced by four to six goals that have a conceptual underpinning. At the chapter’’s end, each goal is divided into subtopics and correlated to relevant Study Questions--tied to OWL--to test comprehension and to aid in study.
Active Figures: Dozens of these animated versions of text art appear in CengageNOW™™ and OWL to help students visualize chemistry in action and master key chapter concepts. Perfect for classroom demonstrations, each figure is paired with a guided exploration and exercise to ensure that students understand the concept being illustrated.
Clear Examples: In-text worked examples follow a four-part structure: a "Problem" statement; a "Strategy" for approaching the problem; a fully worked "Solution"; and where appropriate, a "Comment" on the problem and solution. Students learn how to approach a problem rather than memorize problem types and solution approaches.
