Formula and methodology
Formula: Choose the smallest positive integer coefficients that make the count of every element equal on both sides.
The balancer builds an element matrix and solves its conservation equations with exact rational arithmetic before reducing the coefficients to the smallest whole-number set.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Reactants — Use formulas separated by +. Enter element symbols, integer subscripts, and one level of parentheses; do not enter coefficients.
- Products — Use formulas separated by +, for example H2O.
Worked example
| Input | Value |
|---|---|
| Reactants | H2 + O2 |
| Products | H2O |
Balanced equation: 2 H2 + O2 → 2 H2O.
Assumptions and limits
- Formula syntax supports element symbols, integer subscripts, and one level of round parentheses; charges, hydrates, dot notation, and phase labels are not accepted.
- The entered species are assumed to be the complete reactant and product lists for one line of reaction.
- The result balances atoms only; it does not predict whether a reaction occurs, identify products, or check redox charge balance.
