a shorthand way of describing a chemical change using symbols of elements and formulas of compounds.
a description of a chemical reaction that uses formulas and coefficients to indicate the number of moles of each compound
A chemical equation is a method of expressing chemical reactions in a succinct way. The reactants involved are placed on the left, and the products are placed on the right. Usually an arrow seperates the reactants and products. Oftentimes, specific reaction conditions (temperature, pressure, catalyst, etc.) are placed above or below the arrow symbol.
The mathematical representation of a chemical reaction.
A symbolic representation of the relationship between the reactants and products of a chemical reaction.
an expression representing a chemical reaction; the formulas of the reactants (on the left) are connected by an arrow with the formulas for the products (on the right). (see balanced chemical equation)
A compact notation for describing a chemical change. The formulas of the reactants are added together on the left hand side of the equation; the formulas of the products are added together on the right side. Coefficients are inserted before the formulas to ensure that the equation is balanced. The phase in which each substance is found is usually indicated in parentheses after each formula. For example, 2 H2(g) + O2(g) = 2 H2O(g) indicates that 2 moles of hydrogen gas combine with one mole of oxygen gas to produce two moles of steam.

a written representation of a chemical reaction
Shorthand way of presenting what substances react together and what is produced. It also shows the number of atoms or molecules involved in the reaction.
a representation of a chemical reaction showing the relative numbers of reactant and product molecules.
an expression in which symbols and formulas are used to represent a chemical reaction
The IUPAC Compendium of Chemical Terminology defines chemical reaction equation as a "symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right hand side. The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers.
