Two gases are combined and sealed in a 2.0 L container. The 3.0 L of argon gas and 1.0 L of xenon gas each exert 1.00 atm pressure on the walls of their container. (a) Calculate the partial pressure of each gas in the 2.0 L container.
(b) What is the total pressure in the 2.0 L container?

Barry is applying the principles of relative dating to a building that has been constructed. analyzing a section of the building, barry says that the lowest part of the section must have been constructed the parts above it were constructed. he bases this conclusion on the principle of . also, looking at a crack forming in the building wall, he says that the crack must be the wall. barry used the principle of to arrive at this conclusion.
