Complete the following problems on a separate sheet of paper. Be sure to show ALL work and circle your final answers.
1. How many grams of aluminum are required to react with 35 mL of 2.0 M hydrochloric acid in order to form aluminum chloride and hydrogen gas?
2. How many grams of sodium sulfate are formed with sodium is reacted with 750 mL of a 6.0 M solution of sulfuric acid? Hydrogen gas is another product.
3. What volume of chlorine gas, measured at STP, is necessary to complete react with 4.81 g of sodium metal to form sodium chloride?
4. Propane, C3H8, burns in air to form carbon dioxide and water. What volume of oxygen gas at 25˚C and 1.04 atm is needed for the complete combustion of 5.53 g of propane?
5. If 45 mL of a 1.5 M silver nitrate solution is added to potassium chloride, how many grams of the two products, silver chloride and potassium nitrate, can be formed?
6. How many milliliters of a 0.75 M solution of calcium nitrate will be required to react with 88 g of sodium carbonate, which will form calcium carbonate and sodium nitrate?
7. Ethylene, C2H4, burns in oxygen to form carbon dioxide and water vapor. How many liters of water can be formed if 1.25 liters of ethylene are consumed in this reaction occurring at 32°C and .989 atm?
8. When chlorine gas is added to acetylene, 1,1,2,2-tetrachloroethane is formed as shown in the equation:
2 Cl2 (g) + 1 C2H2 (g) à 1 C2H2Cl4 (l)
How many liters of chlorine gas at 28°C and 772 mmHg will be needed to make 75.0 grams of C2H2Cl4?
9. How many liters of water can be made from 34 grams of oxygen gas and 6.0 grams of hydrogen gas at STP? What is the limiting reactant for this reaction?
10a. How many grams of solid barium sulfate will form when 50.0 mL of 0.40 M sodium sulfate reacts with 25 mL of 0.50 M barium nitrate? Sodium nitrate is also produced by the reaction.
