chemical equation
model of chemical reaction in form of a written equation
AI overview
A chemical equation is a written representation that shows what substances react together and what new substances are created when a chemical reaction occurs. It matters because it allows scientists and students to understand and communicate what happens during chemical reactions in a clear, organized way.

A chemical equation is the symbolic representation (notation) of a chemical reaction in the form of symbols and chemical formulas. The reactant entities are given on the left-hand side, and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. The chemical formulas may be symbolic, structural (pictorial diagrams), or intermixed. The coefficients next to the symbols and formulas of entities are the absolute values of the stoichiometric numbers. The first chemical equation was diagrammed by Jean Beguin in 1615.
