Balancing chemical equations is a core stoichiometry skill: the same number of each type of atom must appear on both sides of a reaction. This tool takes an unbalanced equation such as H2 + O2 -> H2O, parses every compound, builds a conservation matrix for each element, and solves for the smallest whole-number coefficients. It supports parentheses, hydrates, and common arrow notations (->, =, →). Results show the balanced equation plus a reactant and product breakdown — all computed instantly in your browser with no signup.
Chemical equation balancer free — balance reactions like H2 + O2 → H2O with correct coefficients. Instant stoichiometry in your browser, no signup.
Coefficients are the smallest whole-number ratio that conserves each element. For redox or ionic half-equations, enter the full molecular formulas on each side.
