Question 1- All of the following questions refer to this thermochemical equation:
Al2(CO3)3 (s)→ AbO3 (s) + 3 CO2 (g)
AH=+579 kJ
a. How much heat is required to react 5.00 grams of the aluminum carbonate?
b. If 5250 kJ of heat is added to aluminum carbonate, how many grams of aluminum
oxide will be produced?
c. If the carbon dioxide gas produced when 5250 kJ of heat is added to aluminum
carbonate is collected in a 10.5 L container at 37.0 °C, what pressure will the carbon
dioxide exert?
d. The gas in part c is cooled to -20.0 °C after being transferred to a 2.5 L container-
what is its new pressure?
e. Using the principles of Kinetic Molecular Theory, explain why the calculated pressure
in part d is different than the calculated pressure of part c.
Question 2-All of the following questions refer to this thermochemical equation-use
your appendix II for changes in enthalpies of formation:
C6H6 (1) + O2 (g) → CO2 (g) + H20 (g) AH = ??
a. Write the balanced thermochemical equation for the complete combustion of liquid
