This tool finds the correct molecule coefficients to balance chemical reaction equations.
It tries all possible coefficients (from 1 to 7) on all molecules inputted.
It currently has no support for parenthesis.
Example: The "proper" formula (unbalanced)
NO2 + H2O → H3 + O + NO
would become (when putting into the field)
NO2+H2O>H3+O+NO
Solution
Input a formula first.
