This means that the ratio of the amounts of reactants (in moles) is equal to the ratio of the corresponding coefficients in the reaction equation. Substances enter into chemical reactions in quantities proportional to the coefficients in the chemical equation. The chemical reaction equation shows which substances react with each other and in what quantities, as well as what substances are formed and how much of each can be obtained. The field with the limiting reactant is highlighted in pink. In addition, the amounts of unreacted reagents are calculated and the limiting reactant is determined. If you enter in the corresponding fields the amounts of reagents, either as number of moles or weight in grams, then, after pressing the ‘Enter’ key, you will get the amounts of reaction products (in moles and grams). To calculate the amount of reagents you need to take to get a certain amount of a given reaction product, enter that amount either as the number of moles or as its weight in grams in the corresponding field and then press the ‘Enter’ key. In case the original equation was unbalanced, the field with this equation is highlighted in light pink. In what follows is a more detailed syntax guide to our calculator.Īfter you click the ‘Calculate’ button, the equation is automatically balanced and a list of all reactants and reaction products involved in the chemical reaction appears. ) or the asterisk (*) precedes the water formula (e.g.H₂O) which then automatically converted to normal form. H 2O) or with the help of the ‘tiny’ numbers, like ₂ or ₅, (e.g. The indices are denoted using and html tags (e.g.

The chemical reaction equation may include free electrons and electrically charged molecules (ions) as well as hydrated compounds. In addition, the amount of unreacted reagents and the limiting reactant are determined. It also calculates the amounts of reactants and reaction products in both moles and grams. This online Chemical Reaction Calculator checks whether a given chemical equation is balanced and finds the appropriate stoichiometric coefficients.
