(STOY-KEE-AHM-EH-TREE) • Stoichiometry is the part of chemistry that studies amounts of reactants and products that are involved in reactions. • Chemists use a balanced chemical equation as a basis to calculate how much reactant is used or product that is produced in a reaction. • A balanced chemical equation can be interpreted in terms of different quantities, including number of atoms, molecules, or moles. • In a balanced chemical equation, the coefficient in an equation represents not only numbers of individual molecules but also numbers of moles. • The basis for stoichiometry is the law of conservation of mass, which states the mass of the reactants will equal the mass of the products. 2 Cr + 1 Mm + 3 Ch 1 Cr2MmCh3 Balance the equation. 1 3 2 ____N + ____H ____NH 2 2 3 This equation can be looked at with ________ molecule of N2 reacts with one three molecules of H2 to produce __________ molecules two ________________ of NH3. 1 N2 + 3 H2 2 NH3 This equation can be looked at as one mole of N2 reacts with three moles ____________ of H2 to produce two moles of NH3. _________ conversion A mole ratio is a _______________ factor coefficients of a derived from the ______________ balanced chemical equation interpreted in moles terms of ______________. Balance the equation and write all six mole ratios. 3 2 4 ____Fe + ____O ____Fe 2 2O3 * Remember, stoichiometry is based on the law of conservation of mass. Mass of reactants = Mass of products Balance the equation 1 3H8 + ____O 5 3 4 ____C 2 ____CO2 + ____H2O * C6H12O6 + O2 CO2 + H2O H2 + N2 NH3 Al(s) + O2(g) Al2O3(s)
