A chemical reaction is the process in which one or more substances changes to yield one or more different substances. There are five different types of chemical reactions, synthesis, decomposition, single displacement, double displacement, and combustion. In a  __synthesis reaction__, two or more substances combine to produce a new compound. A __decomposition reaction__ is basically the opposite of a synthesis reaction, when a single compound reacts to produce two or more simpler substances. A __single displacement reaction__ is characterized by one element replacing another similar element in a compound; the free element of the reactants displaces the more similar ion of the product’s compound and the other ion becomes the uncombined element. In a __double displacement reaction__ , the positive ions of two compounds replace each other to form two new compounds. Finally, in a __combustion reaction__, a substance combines with some form of oxygen to create one or more oxides, the products in a combustion reaction will usually be carbon dioxide and water.
