Concept Review Questions test students' general understanding of key ideas in the chapter.
Skill-Building Exercises are written in pairs, with one of each pair answered in the back of the book. These exercises begin simply and increase gradually in difficulty.
Problems in Context apply the skills learned to interesting scenarios and examples.
These three types of problems, which are keyed by chapter section, are followed by a group of Comprehensive Problems that are presented in any order, include problems from every section, and often call on concepts and skills learned in earlier chapters.
New Design! Layout and design changes allow for more 'white space' in the margins and easier-to-follow, worked sample problems. Figures and tables are placed even closer to their citations for optimum readability.
New molecular art! Over 50 new pieces of the spectacular molecular art that has been a signature of previous editions are included.
New multimedia icon! Icons in the margin highlight key ideas that are enhanced with an animation located at the On-Line Learning Center.
New coverage of advanced materials! Chapter 12 now contains a brand new discussion of the physical behavior of polymers and an expanded survey of the exciting field of nanotechnology.
New and revised chapter content. Included zero-order kinetics in Chapter 16; refocused the relation of the equilibrium constant to the reaction quotient in Chapter 17; clarified the meaning of entropy and the relation between free energy and work in Chapter 20; and established a consistent method for calculating the potential of electrochemical cells in Chapter 21.
Thinking Logically to Solve Problems. A four-step problem-solving approach is used to facilitate student reasoning, not memorizing, toward a solution.
Plan. After a problem is stated, the steps are verbally planned to show how to move from what is known to what is unknown.
Solve. Next, the plan is executed by naming each calculation step and then carrying out the math.
Check. The next step is to check that the answer makes sense both chemically and mathematically. Sometimes a Comment appears about common pitfalls and alternative approaches.
Practice. A follow-up problem that requires the same concept to solve it appears immediately after the sample problem, and a brief, worked-out solution is provided at the end of the chapter.
3-Level Depictions of Chemical Events. Ground-breaking art program that consistently combines photographs of chemical events with a coordinated molecular view of that event and with the equation that symbolically and quantitatively describes that event.
'Chemical Connections.' Interdisciplinary science boxes appear throughout the book to show how chemistry is related to other sciences. Nearly all biochemical topics occur within this feature as do essays on specific topics in geology, industrial technology, environmental issues, and so forth.
Tools of the Laboratory. Laboratory boxes that describe some of the instruments commonly used in chemical research. The principle behind the measuring instrument pertains directly to the topic at hand in the text.
Galleries. Single or multi-page illustrated summaries of concepts and applications. For example, Chapter 11 has a full-page gallery that applies the properties of liquids to everyday events. New to 3e, the gallery on batteries (Chapter 21) now includes the nickel-metal hydride type and the latest information on H2-based fuel cells, all based on expert input.
Interchapter. Found between Chapters 13 and 14, this is a specially designed, multi-page gallery of text and art that reviews and visually summarizes the major ideas presented in the first semester.
Family Portraits of the Elements. Two-page summaries of the properties of each group of elements include photographs of the elements in each group and summary graphs.
