Module 8 Pt2 91 Law of conservation of massin a chemical reaction the total mass of the reactants is equal to the total mass of the products matter is never lost nor gained Mold Mole factora conversion factor that relates the number of moles of two compounds in an equation derived from their coefficients See page 283 for example problem 92 When we have the balanced chemical equation for a reaction we can use the mass of one substance A in the reaction to calculate the massive another substance B in the reaction See page 285 93 Limitinq reactant the reactant used during a chemical reaction which limits the amount of products that can form 0 The reactant that does not completely react and is leftover is called the excess reactant 0 Example suppose you have enough bread to make three peanut butter sandwiches but only enough peanut butter to make one gt In this case the peanut butter would be the limiting reactant gt And the bread would be the excess reactant 94 Theoretical yield the maximum amount of product reaction can produce from a given amount of reactant Actual yield the actual amount of product produced by a reaction Percent yield the ratio of the actual yield for reaction to the theoretical yield possible for the reaction f actual yield W Pcrccm y1cld 91 gtlt l quot39 theoretical yield
