How Chemical Equation Balancing Works
A balanced chemical equation has equal numbers of each element on both sides, satisfying the Law of Conservation of Mass.
This tool uses Gaussian elimination on the stoichiometry matrix to find the smallest integer coefficients that balance the equation. It handles complex reactions including organic combustion, redox reactions, and reactions with polyatomic ions.
Tips
- Use standard chemical notation:
H2O,Ca(OH)2,Fe2O3 - Separate reactants and products with
->or= - Separate compounds with
+ - Parentheses for polyatomic groups:
Ca3(PO4)2
