An all-encompassing practice problem for Ch. 5…A.P. Chem A flammable gas made only of carbon and hydrogen is generated by certain anaerobic bacterium cultures in marshlands and areas where sewage drains. A pure sample of this gas is found to effuse through a certain porous barrier in 1.50 minutes. Under identical circumstances of temperature and pressure, it takes an equal volume of bromine gas 4.73 minutes to effuse. This gas is also shown to react with oxygen to produce two products; one is carbon dioxide. If mL of this gas (from a container which is stored at STP) is reacted with mL of O2 stored at STP, what volume of carbon dioxide, in mL, is produced if, after the reaction takes place, the CO2 is found to exist at 25. 0° C and torr. If this CO2 is collected and stored in a container to which a gram sample of SO2 is added, what would be the total pressure of the gas sample mixture? What would be the mole fraction of each gas? What about the partial pressure of each and what would be the speed (rms velocity) of each? Finally, make a description in words of what these gases are behaving like in that container.

Write the balanced chemical reaction…
CH4(g) O2(g) → CO2(g) H2O(g)
Now do the stoichiometry…find the limiting reactant.
Using the relationship that 1 mole of any gas at STP has a volume of 22.4 L you get:
0.2000L CH4 (1mol/22.4L) = mol CH4 and
0.1500L O2 (1 mol/22.4L) = mol O2
L.R.
(1 mol CO2/2 mol O2)
= mol CO2
Plugging into the ideal gas law: V = nRT/P
VCO2= 84.1 mL

This sample of gas can be described as a mixture of dimensionless particles of the gases carbon dioxide and sulfur dioxide which are moving at average speeds of 411 m/s and 340 m/s respectively without interacting with each other while colliding with their container walls 100% elastically to create a pressure of 1180 torr.
