Free online chemical equation balancer: automatically assign the smallest integer coefficients to reactants and products, supporting element symbols, subscripts and parentheses. A staple for chemistry study and homework checks; all calculated locally.
Join reactants and products with +, and separate the two sides with = or ->. Element symbols are case-sensitive (e.g. Fe, Cl); subscripts and parentheses are supported (e.g. Ca(OH)2), and state labels (s)(l)(g)(aq) may be included.
