Under certain circumstances, carbon dioxide, CO2 (g) can be made to react with hydrogen gas, H2 (g) to produce methane, CH4 (g) and water vapour H2O (g).
CO2 (g) + 4H2 (g) → CH4 (g) + 2H2O (g)
How many moles of methane are produced when 36.6 moles of carbon dioxide gas react with excess hydrogen gas.
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 30.6 moles of water.
Express ye answer with the appropriate units.
