Under certain circumstances, carbon dioxide,CO2(g), can be made to react with hydrogen gas,H2(g), to produce methane, CH4(g), and water vapor,H2O(g):
CO2(g)+4H2(g)→CH4(g)+2H2O(g)
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 76.6 moles of water vapor?
If one collects the first liter of gas that moves from the original room into the evacuated room, approximately what would you expect its composition to be? Would it be the same as regular air?
