3)Methanol can be produced as follows: CO (g) + 2 H2 (g) + CH4O (g) If 250.0 L of hydrogen gas are reacted with excess CO at STP, how many grams of CH40 can be produced?

Equal volumes of h2 and o2 are placed in a balloon and then ignited. assuming that the reaction goes to completion, which gas will remain in excess? 2h2 + o2 → 2h2o a. both are in equal proportion b. oxygen c. water d. hydrogen
