Reactants Products Before reaction 3 mol N, 6 mol H, O mol NH, After reaction 1 mol N2 O mol H2 4 mol NH, Reaction in presence of limiting reagent. Ammonia, NH3, is created from the reactants N2 (shown in green) and H2 (shown in white) according to the following balanced chemical equation. In the example above you begin with 3 mol of nitrogen gas and 6 mol of hydrogen gas. N2+3H2----> 2NH3 Which is the limiting reactant? You can tell that hydrogen is the limiting reactant because all of it was used up, but there is some leftover (excess) nitrogen in the diagram when the reaction is complete Since the mole ratios match up perfectly between the reactants neither of them is limiting. You can tell that ammonium is the limiting reactant because there were 0 moles of it before the reaction started. You can tell that nitrogen gas is the limiting reactant because there were fewer moles of it with which to begin.

Converting between quantities To convert from a given quantity of one reactant or product to the quantity of another reactant or product • First, convert the given quantity to moles. Use molar masses to convert masses to moles, and use Avogadro's number (6.02 x 10 particles per mole) to convert number of particles to moles. • Next, convert moles of the given reactant or product to moles of the desired reactant or product using the coefficients of the balanced chemical equation. For example, in the chemical equation2H2 + O2-2H20the coefficients tell us that 2 mol of H2 reacts with 1 mol of Oz to produce 2 mol of H20. • Finally, convert moles of the desired reactant or product back to the desired units. Again, use molar masses to convert from moles to masses, and use Avogadro's number to convert from moles to number of particles.
