Enter a chemical equation to balance. Use element symbols (Fe, NaOH, Ca(OH)2) or
chemical names (calcium hydroxide). Separate reactants and products with = or →.
Enter only the reactants. The system will predict the products and balance automatically. Works best for common reaction types.
Compute moles and mass of all compounds from a known amount. Enter a balanced equation (or it will auto-balance).
Find the limiting reagent and theoretical yield. Enter mass for all reactants.
Calculate molar mass and elemental composition of any compound.
