Stoichiometry and Limiting ReagentThe limiting reagent is the reagent that determines the amount of product that can be formed by a reaction. The reaction occurs only until the limiting-reagent is used up. Keep in mind that the reactant that is present in the smaller amount by mass or volume isn’t always limiting. Excess reagent is the reactant that is not completely used up in a reaction. Stoichiometry is the calculation of amounts of substances involved in chemical reactions. Chemists use this method to compute the amounts of reactants and products by using the ratios of moles or representative particles. When solving stoichiometric problems, the given quantity is first converted to moles. Then the mole ratio from the balanced equation is used to calculate the moles of the desired substance. Finally, the moles are converted to any other unit of measurement that is related to the unit mole. Examples will be added soon! Stoichiometry - Back to Chemistry Help
