Balanced Chemical Equations Calculator
Enter an unbalanced chemical equation (e.g. C3H8 + O2 -> CO2 + H2O). The solver uses exact rational arithmetic and returns the smallest integer coefficients.
H2 + O2 -> H2O Fe + O2 -> Fe2O3 C3H8 + O2 -> CO2 + H2O KMnO4 + HCl -> KCl + MnCl2 + H2O + Cl2 NaOH + H2SO4 -> Na2SO4 + H2O
Balancing chemical equations is one of the most important skills in chemistry. It ensures that the law of conservation of mass is followed, meaning atoms are neither created nor destroyed during a reaction. While doing this manually can be time-consuming and prone to mistakes, the Balanced Equations Calculator makes it quick, accurate, and effortless.
This article will explain what the tool does, how to use it step by step, provide a real-world example, share its benefits and features, and answer the most common questions about chemical equation balancing.
