There are many types of chemical reactions‚ five general ones of which I will be describing. Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter nor energy is created or destroyed in a chemical reaction‚ only changed. There are so many chemical reactions that it is helpful to classify them into 5 general types‚ which include the following: synthesis‚ combustion‚ decomposition‚ single-replacement‚ and double-replacement
