	Chemical reaction - Wikipedia, the free encyclopedia
		Chemical reactions are characterized by a chemical change and it yields one or more products which are, in general, different from the reactants.
		Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions.
		Chemical reactions may be classified in different ways depending on the particular aspect considered for elaborating the division, or on the branch of Chemistry which the classification originates from.
