What is the definition of 299-300 Composition stoichiometry deals with the mass 299-300 stoichiometry? relationships of elements in compounds Reaction stoichiometry involves the mass relationships between reactants and products in a chemical reaction To solve stoichiometric problems, you need to use the mole What is the importance of 300-301 A mole ratio is a conversion factor that relates the 300-301 mole ratios in stoichiometric amounts in moles of any 2 substances involved in a calculations? chemical reaction EXAMPLE: The mole ratio of aluminum to oxygen in the reaction 2Al2O3 -> 4Al + 3O2 is 4:3 How do you do 304-311 use the mole map 304-311 stoichiometric calculations? How do you determine which 312-316 The limiting reactant is the reactant that limits the 312-316 reactant is the limiting amount of the other reactant that can combine and the reactant? amount of product that can form in a chem rxn The substance that is not used up completely in a rxn is called the excess reactant To determine the limiting reactant, convert the amt. of each reactant to moles. The smaller mole is the limiting reactant
