Chemical Equation Balancer
Balance chemical equations and verify atom counts on both sides.
Built for chemistry learners
Enter reactants and products with an equals sign, arrow, or ->. The workspace balances coefficients, verifies atoms, estimates stoichiometry, and shows the algebra behind the answer.

What is Chemical Equation Balancer?
Chemical Equation Balancer helps students solve common chemistry problems faster while still showing the formula behind the answer. It is intended for university chemistry, pre-med study, and general chemistry practice.
Manual calculation is still important: identify the known variables, convert units before substitution, apply the equation, and check whether the result is chemically reasonable. The most common mistakes are inconsistent units, rounded constants too early, and skipping the interpretation step.
Practice Prompt
Try changing the default values and ask the lower-right chemistry chat why the result increased or decreased. That turns the calculator from a number machine into a study loop.
Chemical Equation Balancer is an educational chemistry tool for balance chemical equations and verify atom counts on both sides.
It uses standard textbook equations and atomic masses. For laboratory or clinical decisions, verify with official protocols.
Yes, when OPENAI_API_KEY is configured, the lower-right chemistry chat can explain steps and clarify concepts through a server-side API route.
Yes. The tool layout collapses to one column with mobile-safe inputs.
