| Also Known As | Chemical equation, reaction equation, balanced equation |
What is Equation of Reaction?
A symbolic representation of a chemical reaction showing the reactants, products, and their relative amounts using chemical formulas and coefficients. A balanced equation obeys the law of conservation of mass. It may also show state symbols (s, l, g, aq).

A symbolic representation of a chemical reaction showing the reactants, products, and their relative amounts using chemical formulas and coefficients. A balanced equation obeys the law of conservation of mass. It may also show state symbols (s, l, g, aq).
Equations of reaction are the universal language of chemistry. They are used in stoichiometry calculations, reaction mechanism description, thermochemical calculations (ΔH per equation written), and regulatory chemistry (predicting combustion products, waste streams).
Incorrectly written or unbalanced equations can lead to wrong calculations of reagent quantities, potentially producing excess hazardous by-products or missing required stoichiometric amounts. Always check balance before use in practical chemistry.
