Use the following equation (unbalanced) to solve the following series of problems.
Ca(s) + O2(g) -->CaO(s)
What mass of calcium will react with oxygen gas in a 10.500 L container at a pressure of 10.0 atm and 500.°C?
If 25.7 g of calcium reacts with oxygen gas, how many L of oxygen gas will be consumed at STP?
How many g of CaO can be made from 150.0 mL of oxygen gas at 140°C and 1.52 atm?
If 1.5 kg of Ca is reacted, how many mL of oxygen gas are required at 85.0°C and 5.00 atm?

CaO(s) reacts with SO2 (g) according to the following equation:
CaO(s) + SO2 = CaSO3(s). A 8.85 g mixture containing CaO(s) is
placed in a 3.0L container. The container is filled with SO2(g) to
a pressure of 749 torr, at 20 C. After the reaction has gone to
completion, the pressue inside the flask is 390 torr also at 20 C.
What is the mass of CaSO3(s) produced? assume that only CaO(s) in
the mixture reacts with SO2(g).
