Enter a chemical equation using -> or = to separate reactants and products, and + between compounds. For example: H2 + O2 -> H2O. The calculator tries integer coefficients to balance all elements.
About the Chemical Equation Balancer
Balancing chemical equations is a core skill in chemistry. Every balanced equation must have equal numbers of each type of atom on both sides, following the law of conservation of mass. This calculator uses a brute-force approach suitable for common reactions.
Frequently Asked Questions
How does equation balancing work?
Balancing ensures the same number of each type of atom appears on both sides of the equation. This satisfies the law of conservation of mass. The calculator tries integer coefficients until all elements balance.
What equations can this handle?
This calculator handles equations with up to 6 compounds and coefficients up to 10. For very complex equations with large coefficients, a more advanced matrix-based solver may be needed.
Why must chemical equations be balanced?
The law of conservation of mass requires that atoms are neither created nor destroyed in a chemical reaction. A balanced equation ensures the same number of each type of atom on both sides, reflecting this fundamental law.
