CHEMISTRY TOOL

Chemical Equation Balancer

Enter a chemical reaction and balance reactants and products while keeping coefficients and atom counts easy to review.

Example problems

H2 + O2 -> H2O
CH4 + O2 -> CO2 + H2O
Fe + O2 -> Fe2O3
Na + Cl2 -> NaCl

Why chemical equations must balance

A balanced chemical equation preserves the number of atoms of each element on both sides. Edu Companion finds whole-number coefficients that satisfy conservation of matter for supported reactions.

Frequently asked questions

How do I enter a chemical reaction?

Use a reaction arrow such as -> between reactants and products, for example CH4 + O2 -> CO2 + H2O.

Why are coefficients changed instead of subscripts?

Coefficients change the amount of each substance without changing the chemical identity of the compounds. Subscripts are part of the compound formula and should not be altered to balance a reaction.

Can the balancer explain the result?

The chemistry workspace is designed to return a balanced equation and student-friendly guidance for supported reactions.
