Stoichiometry Homework Problem Set


  1. Balance the following equations. Give the names of the reactants and the products. Given 10.0 grams of each reactant. How many grams of each product could be produced? What is the total mass of reactants and products when the reaction is complete?
    1. LiOH (s) + H2SO4 (aq) --> H2O (l) + Li2SO4 (aq)
    2. Mg(OH)2 (aq) + H3PO4 (l) --> Mg3(PO4)2 (aq) + H2O (l)
    3. CH4 (g) + O2 (g) --> CO2 (g) + H2O (g)
    4. C8H18 (l) + O2 (g) --> CO2 (g) + H2O (g)
    5. NaCl (aq) + AgNO3 (aq) --> AgCl (s) + NaNO3 (aq)
    6. CH3COOH (aq) + NaHCO3 (s) --> CO2 (g) + H2O (l) + NaCH3COO (aq)
  2. Balance the following equations. Starting with 25.0 grams of each reactant, how many grams of each product could be produced? What is the total mass of reactants and products when the reaction is complete?
