CHAPTER 8 Chemical Reactions and Thermochemistry

The following terms summarize all the concepts and ideas that were introduced in this chapter. You should be able to explain their meaning and how you would use them in chemistry. They appear in boldface type in this chapter to draw your attention to them. The boldface type also makes it easier for you to look them up if you need to. You could also use the search or “Google” action on your computer to get a quick and expanded explanation of these terms, laws, and formulas.

combination reaction		heat of formation
decomposition reaction		hydrolysis reaction
double replacement reaction		molar heat of formation
enthalpy		single replacement reaction
entropy		standard enthalpy of formation
heat of combustion
