Notes, CP Chemistry, Chapter 9, Chemical Reactions revised 2/24/13 9.1, Reactions and Equations, pp. 282-288 Chemical reactions are the processes by which atoms of one or more substances are rearranged to form different substances. They are chemical changes. All reactions involve some sort of physical changed. Thermochemistry is a branch of chemistry that qualitatively and quantitatively describes the energy changes that occur during chemical reactions. Energy is the capacity to do work. Mechanical work is the amount of energy required to move an object a given distance when opposed by a force. Three classifications of chemical reactions will be reviewed in this section. Predicting the products in some of them may be difficult, but the reactions are still easy to recognize. A composition reaction (sometimes also called a combination reaction or a synthesis reaction) produces a single substance from multiple reactants. A single ... AP CHEMISTRY.
