Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

Trimethylamine, (CH3)3N, is a common reagent. It interacts
readily with diborane gas, B₂H6. The latter dissociates to BH3
and this forms a complex with the amine, (CH3)3N→BH3.
The reaction between trimethylamine and borane is shown.
