The reaction of methane and water is a way to prepare hydrogen according to CH4 (g) + H2O = Co2 (g) + H2 (g) a) If 995 g of CH4 reacts with 2510 g of water, how many moles of reactants and products are there when the reaction is finished? Identify the limiting reagent in the reaction. b) If only 228 g of H2 are produced what is the % yield of gas?
