  1. PROBLEM A: 2C2H6(G) + 7O2(G) --> 4CO2(G) + 6H2O(L)If exactly 15.6 moles of ethane gas combusts, how many moles of oxygen are used?

  2. PROBLEM B: 4NH3(G) + 5O2(G) --> 4NO(G) + 6H2O(L) If exactly 649.6 L of NO(G) form, how many liters of O2 are used?

  3. PROBLEM C:2C8H18(L) + 25O2(G) --> 16CO2(G) +18H2O(G) During this combustion, 125 g of oxygen are used up. How many g of H2O are produced?

  4. PROBLEM D: 2N2(G) + 5O2(G) --> 2N2O5(G) 105 g of N2 react with oxygen to form dinitrogenpentoxide. How many molecules of N2O5actually form in this reaction?

  5. PROBLEM E: 4Fe(S) + 3O2(G) --> 2Fe2O3(S) In a synthesis reaction between a truck and the air 12,525 moles of oxygen will convert how many moles of iron into rust?

  6. PROBLEM F: 2NO2(G) + 7H2(G) --> 2NH3(G) + 4H2O(L) In a test tube reaction, 0.135 moles of H2 will react to form how many grams of NH3?
