Question

Core Chemistry Skill: Using Mole-Mole Factors Under certain circumslances, carbon dioxide, CO,(g), can be made to react with hydrogen gas, Ha(g), to produce methane, CH, ( CO2 (g)+4H3 (g)-CH, (g) + 2H ,O(g) Part A How many moles of methane are produced when 82.6 moles of carbon dioxide gas react with excess hydrogen gas? Express your answer with the appropriate units. You did not open hints for this part ANSWER umber of taxis art B How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 19.1 moles of water vapor? Express your answer with the appropriate units. You did not open hints for this part ANSWER

Answer 1

CO₂(g) + 4H2(g) Chy (g) + 2 H₂O(g) (A) By sen, Imole CO₂ forms a Imole methane (CH4) =) 822.5 mol Co, will form = 182.5 mol ) methane (B) By snn, 2 mol H₂O formed by = 4 mol H₂ of 19.1 mol H20 will be formed by + ( x 19.1) mol H2 - 38.2 moles of Hydrogen gas needed.
