6) How many grams of cadmium metal are required to react with excess hydrochloric acid to produce 6.50 liters of hydrogen gas at STP?
7) How many liters of carbon monoxide gas at STP are required to react with 4.80g of oxygen gas to produce carbon dioxide gas as the only product?
8) calculate the number of liters of oxygen gas needed to react with excess nitrogen gas in a synthesis reaction to produce 15 liters of dinitrogen trioxide gas. Assume all gases are measured at standard temperature and pressure.

6. Cd(s) + 2 HCl(aq) ---------> CdCl2(aq) + H2
? g Cd = 6.5 L H2 x 112 g Cd/ 22.4 L H2 = 12.9 g Cd
7. 2 CO(g) + O2(g) -----------> 2 CO2(g)
? L CO = 4.80 g O2 x 44.8 L CO/ 32.0 g O2 = 6.72 L8.
8. 2 N2(g) + 3 O2(g) -----------> 2 N2O3(g)
? L O2 = 15 L N2O3 x 67.2 L O2 / 44.8 L N2O3 = 22.5 L O2
