A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5015 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.421 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant. Xch4=

Much of the world’s natural gas is stored in permafrost and in deep cold ocean bed deposits as methane hydrate, also called methane clathrate or, inaccurately, methane ice. Methane hydrate is an ice-like crystal in which individual molecules of methane are enclosed in a crystalline “cage” structure formed from frozen water molecules (and sometimes clays). The composition of methane hydrate is 1 mole of methane to 5.75 moles water. In clathrate deposits containing methane hydrates, around 1% by weight of...
