This program does stoichiometric calculations on a balanced chemical equation. If you are having trouble balancing an equation or just don't feel like balancing it yourself, use the Chemical Equation Balancer.

Conventional notation is used, i.e. - the first letter of an element is capitalized and the second is a small letter. Enter the equation as shown below. There must be one space before and after the + and -> signs. When using scientific notation, there must be one space before and after the x sign.

After entering the balanced equation, you can specify any one of the reactants and its amount. Note that because
SO2 is the first reactant in the equation, it appears as the first reactant in the list. Also note the input format for scientific notation.

At the present time, redox reactions, limiting reactant problems, and chemical equations containing hydrates can not be solved.
