Chemistry
The twelfth edition continues the tradition by pro¬viding a firm foundation in chemical concepts and principles and to instill in students an appreciation of the vital part chemistry plays in our daily life. It is the responsibility of the textbook authors to assist both in¬structors and their students in their pursuit of this objec¬tive by presenting a broad range of topics in a logical manner. We try to strike a balance between theory and application and to illustrate basic principles with every¬day examples whenever possible.
As in previous editions, our goal is to create a text that is clear in explaining abstract concepts, concise so that it does not overburden students with unnecessary ex¬traneous information, yet comprehensive enough so that it prepares students to move on to the next level of learn¬ing. The encouraging feedback we have received from instructors and students has convinced us that this approach is effective.
The art program has been extensively revised in this edition. Many of the laboratory apparatuses and scientific instruments were redrawn to enhance the realism of the components. Several of the drawings were updated to re¬flect advances in the science and applications described in the text; see, for example, the lithium-ion battery de¬picted in Figure 18.10. Molecular structures were created using ChemDraw, the gold standard in chemical drawing software. Not only do these structures introduce students to the convention used to represent chemical structures in three dimensions that they will see in further coursework, they also provide better continuity with the ChemDraw application they will use in Connect, the online home¬work and practice system for our text.
In addition to revising the art program, over 100 new photographs are added in this edition. These photos pro¬vide a striking look at processes that can be understood by studying the underlying chemistry (see, for example, Figure 19.15, which shows the latest attempt of using lasers to induce nuclear fusion).
