Boxes and margin notes

Principles of General Chemistry achieves authoritative topic coverage in 300 fewer pages than its parent text, thereby appealing to today s efficiency-minded instructors and value-conscious students. To accomplish this shortening, most of the material in the boxed applications essays and margin notes was removed, thereby allowing instructors to include their own favorite examples. 

The book contains margin notes and two types of boxes, which are designed to enable the reader to identify certain types of information easily. 

The other things you should look out for are the margin notes and boxes. There are four sorts, and they have all appeared at least once in this chapter. 

The term equilibrium template reaction is defined in Box 5.4, and an example is provided in Scheme 5.3, The term kinetic template reaction is defined in the margin note on page 93 and an example is provided in Scheme 5.4. 

Chemical Connections boxes present applications of chemistry in various fields and in our daily lives. Margin notes in f e Instructor s Annotated Edition also highlight many more Chemical Connections available on the student website. 

Chapter Openers show the relevance of analytical chemistry to the real world and to other disciplines of science. Boxes discuss interesting topics related to what you are currently studying, or they amplify points from the text. Demonstration boxes describe classroom demonstrations, and Color Plates near the center of the book illustrate demonstrations or other points. Marginal Notes amplify what is in the text. Spreadsheets are introduced in Chapter 3, and applications appear throughout the book. You can study this book without ever using a spreadsheet, but your experience will be enriched by spreadsheets and they will serve you well outside of chemistry. Problems intended to be worked on a spreadsheet are marked by an icon. You might choose to work more problems with a spreadsheet than those that are marked. 

New margin notes and Stop Think boxes clarify more difficult concepts to students. 

Get the p L values from the data given in Appendix C. Note that 4-BuPh (Tm = 99°C) is a solid at 25°C (use Eq. 4-40 to estimate p L from p s). Calculate Vix using the method described in Box 5.1. Get the nDi values of the compounds from Lide (1995). Use the ah and Ph and n, values given in Tables 4.3 and 5.5. The resulting data sets for the three compounds are given in the margin. Recall that G -RTIn y w. Insertion of the respective values into Eq. 5-22 yields the following result ... 

As our Fig. 17.1 splitter box has a diameter D of 2.0 m and the height to the water level h is the same, the contained volume is 6.3 m and the power per cubic metre is 4.5/6.3 = 0.7 kW. This exceeds the value of 0.55 kW for the existing tank, so there should be no settlement, and the margin of excess is not too great, so there should not be excessive splashing. We include also the part of the plant hydraulic diagram for this section in Fig. 17.2. (Note these diagrams can be and are presented...
