Answer/calculate the following problems showing all appropriate work (review example of work for specifics).

A) Oxygen is produced by the reaction of sodium peroxide and water according to the following reaction:
2 Na2O2 (s) + 2 H2O1 (l) --> 1 O2 (g) + 4 Na1(OH)1
If 25.3g of sodium peroxide and 14.7g of water reacts:

a. Determine the limiting reactant .
b. Mass (in g) of the two products that are formed in this reaction.
c. Determine the excess reactant and how many grams are left after the reaction.


B) 27.7 liters of oxygen gas are added to 110. liters of hydrogen chloride gas in the following reaction:
4 HCl(g)+ 1 O2 (g) --> 2 Cl2 (g) + 2 H2O1 (g)

a. Determine the limiting reactant
b. Volume of (in liters) of the two products that is formed in this reaction.
c. Determine the excess reactant and how many liters are left after the reaction.


C) Tin is produced from its ore (Tin (IV) oxide) in the following reaction:
1 SnO2 (s) + 1 C(s) --> 1 Sn(s) + 1 CO2 (g)
If the 25.3 grams of Tin (IV) oxide and 14.7 grams of carbon reacts:

a. Determine the limiting reactant.
b. Mass (units of grams) of the two products that is formed in this reaction.
c. Determine the excess reactant and how many grams are left after the reaction.
