Limiting Reactants: The reactant that restricts the amount of product obtained is called the limiting reactant. The concept of limiting reactants applies to reactions carried out in solution as well as to reactions involving pure substances. How To Calculate Limiting Reagents?:
1. Enter any known value for each reactant, the limiting reagent will be highlighted.
2. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
3. Ionic charges are not yet supported and will be ignored.
4. Replace immutable groups in compounds to avoid ambiguity.
For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
5. Compound states [like (s) (aq) or (g)] are not required.
6. You can use parenthesis () or brackets [].

This limiting reagent calculator provides you the most reliable results in a fraction of seconds without any error that arises in the manual calculation.
