1. Ammonia gas can be prepared by the reaction of a metal oxide such as CaO with NH4Cl. Use atomic masses: N: 14.01; H: 1.01; O: 16.00; Ca: 40.08
CaO (s) + NH4Cl (s) à NH3 (g) + H2O (g) + CaCl2 (s)
a. Balance the above equation.
b. If 11.2 g of CaO and 22.4 g of NH4Cl are mixed, which reactant is the limiting reagent?
c. What is the mass of NH3 to be produced?
d. How much the excess reactant remains after the reaction is complete?
2. 55.00 mL of 1.482 M H2SO4 solution and 10.00 mL of 0.269 M NaOH solution are combined, and then diluted with water until the total volume is 250.00 mL. What is the molarity of the final H2SO4 solution?
