Aluminum chloride, a white powder, is an important chemical produced industrially by heating a mixture of aluminum metal and chlorine gas. Write a balanced molecular equation with physical states for what has just been described. Predict the theoretical yield of aluminum chloride, in moles, when 351 g of aluminum metal are put in presence of 1,310 g of chlorine. Show all work. If the reaction was carried out at 650 °C, what volume would the original amount of chlorine have occupied at 10.0 bar? Show all work.

Gas is trapped inside of a cell with volume 150 m3. The gas exerts 7300 Pa of pressure against the walls of the cell. A machine then expands the cell and gives off 290 kJ of heat to the gas during the process. If the internal energy changed by 97 kJ, what is the final volume of the cell? Assume the pressure stays constant. 120 m3 210 m3 97 m3 180 m3 200 m3

Assuming constant pressure, a gas has a final volume of 15 L. If the temperature increases from 330 K to 450 K, find the initial volume. Show all work in the space provided, and then write your final answer on the short line.

21 Consider the combustion of in oxygen gas to produce carbon dioxide gas and water vapor. In an experiment, 0.1063 g of C₅H₈ is combusted to produce enough heat to raise the temperature of 150.0 g of water by 7.632 °C. C₅H₈ (l) + 7 O₂ (g) → 5 CO₂ (g) + 4 H₂O (g) d If 4790 J of heat were absorbed by the water, then how much heat, in J, was produced by the combustion of C₅H₈? (include the appropriate sign)

Write a balanced thermochemical equation with phase labels for the Haber process with the heat energy as part of the equation.

1a. Calculate the pressure of a sample of 1 mole of argon gas in a 0.1500 L flask at -10.2 ℃ using the ideal gas law and the Van der Waals equation. The a value for argon is 1.34 (L 2 ∙ atm/mol2 ) and the b value is 0.0322 (L/mol). Show all work Ideal pressure= ? real pressure =? 1b.Why is there a difference in the real gas pressure and the ideal pressure? Explain what assumption(s) of the kinetic molecular theory of gases break down under these conditions.
