  1. B2O3 + 3 H2O ---> 2 H3BO3 • If diboron trioxide is reacted with water, the product is boric acid. What mass of boric acid is obtained from the full reaction of 6.992 g of diboron trioxide?

  2. 17 H2 + 8 CO ---> C8H18 + 8 H2O • Synthesis gas, a mixture of hydrogen and carbon monoxide, can be heated to temperatures between 200 and 300 degrees Celsius in the presence of a catalyst. Octane, C8H18, and water are produced. What mass of water is obtained from the full reaction of 7201.5 g of carbon monoxide?

  3. 2 PbS + 3 O2 ---> 2 PbO + 2 SO2 • In the metallurgy of galena, or lead(II) sulfide, the principal lead containing ore, the first step is the conversion of the mineral to lead(II) oxide by reaction with oxygen. Sulfur dioxide is also produced. What mass of lead(II) oxide is obtained from the full reaction of 236 L of oxygen at STP?

  4. 8 HNO3 + 3 Cu ---> 3 Cu(NO3)2 + 4 H2O + 2 NO • In moderately concentrated nitric acid, copper will react to produce copper(II) nitrate, water, and nitrogen monoxide. What volume of nitrogen monoxide is produced with 412 L of water vapor?

  5. If excess ammonium sulfate reacts with 20.0 g of calcium hydroxide, how many grams of ammonia are produced?

  6. If excess sulfuric acid reacts with 30.0 g of sodium chloride, how many grams of hydrogen chloride are produced?

  7. How many grams of copper(II) oxide can be reduced to copper metal with 10.0 L of H2?
