The minimum number of reactant substances that can be involved in a chemical reaction is one type. One type of reaction that involves the splitting of a single reactant substance into two or more products is known as a decomposition reaction. read more
Chemical equations show the reactants and products, as well as other factors such as energy changes, catalysts, and so on. With these equations, an arrow is used to indicate that a chemical reaction has taken place. read more
Another example of a reactant is found in the equation 2 H 2 O → 2 H 2 + O 2 where water produces both oxygen and hydrogen gas. In this reaction, the reactant is H 2 O, the water, and the products are the gases H 2 and O 2. read more
Reactants and Products in Chemical Reactions In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. read more
