This study analysed the distribution of questions from the gas law chapters of four high school and four college chemistry textbooks based on six variables—Book Type (secondaryversusintroductory college), Cognitive Skill (lower-orderversushigher-order), Question Format (calculationversusmultiple-choiceversusshort-answer), Question Placement (in-chapterversusend-of-chapterversustest-bank), Question Type (qualitativeversusquantitative), and Representation (macroscopicversusparticulateversussymbolic). The questions in these chapters were homogeneously distributed for the Cognitive Skill and the Representation variables, but showed differences in question distribution based on the Book Type, Question Format, Question Placement, and Question Type variables. The loglinear analysis method used in this study provides one way to analyse the distribution of different types of questions appearing in chemistry textbooks, and these differences in question distribution can be helpful for textbook authors to evaluate the types of questions appearing in their textbooks and how they are presented, and can be helpful for chemistry instructors to determine how they need to adapt their instructional lessons to prepare students for course examinations or college/career placement examinations.

Illustrated with remarkable new full-color images--indeed, one or more on every page--and written by one of the world's leading authorities on the subject, Reactions offers a compact, pain-free tour of the inner workings of chemistry. Reactions begins with the chemical formula almost everyone knows--the formula for water, H2O--a molecule with an "almost laughably simple chemical composition." But Atkins shows that water is also rather miraculous--it is the only substance whose solid form is less dense than its liquid (hence ice floats in water)--and incredibly central to many chemical reactions, as it is an excellent solvent, being able to dissolve gases and many solids. Moreover, Atkins tells us that water is actually chemically aggressive, and can react with and destroy the compounds dissolved in it, and he shows us what happens at the molecular level when water turns to ice--and when it melts. Moving beyond water, Atkins slowly builds up a toolkit of basic chemical processes, including precipitation (perhaps the simplest of all chemical reactions), combustion, reduction, corrosion, electrolysis, and catalysis. He then shows how these fundamental tools can be brought together in more complex processes such as photosynthesis, radical polymerization, vision, enzyme control, and synthesis. Peter Atkins is the world-renowned author of numerous best-selling chemistry textbooks for students. In this crystal-clear, attractively illustrated, and insightful volume, he provides a fantastic introductory tour--in just a few hundred colorful and lively pages - for anyone with a passing or serious interest in chemistry.
