Frequently Asked Questions
A balanced chemical equation has the same number of atoms of each element on both sides of the equation.
Enter the reactants and products as comma-separated chemical formulas (e.g., H2, O2) and list the elements involved (e.g., H, O). Then click Balance Equation.
Ensure your formulas are correctly capitalized (e.g., H2, not h2) and that you list all elements present. The calculator works for simple equations.
