Chapter 12: Thermochemistry

Chemical reactions involve the change of one or more substances into one or more other substances. But reactions also involve changes in energy. By careful measurement, these energy changes can be determined. In Chapter 12, we learn the relationship between chemical reactions and the energy changes that accompany them.
