Up to 20 species. Equations that combine several independent reactions are reported rather than balanced arbitrarily. Balancing does not say whether a reaction happens. Everything is calculated in your browser; nothing you type is uploaded.
Element (and charge) counts form a matrix whose null space is found with exact fractions; the solution is scaled to the smallest whole-number coefficients.
C3H8 + O2 = CO2 + H2O becomes C3H8 + 5O2 → 3CO2 + 4H2O; MnO4^- + Fe^2+ + H^+ is balanced with 5 Fe and 8 H⁺.
