How do chemical bonds relate to chemical reactions?
A chemical reaction involves the making and breaking of strong chemical bonds.
Chemical reactions are characterized by the formation of new substances, and the making and breaking of strong chemical bonds. In practice it is usually fairly easy to discriminate between a chemical change, new substances formed, and a phase change, where bonds may have been broken but no new substances formed.
Examples of chemical reactivity where chemical bonds are manifestly formed include hydrocarbon combustion, the which drives our industrial society, and in which
