1) how many grams of co are needed to react with an excess of fe2o3 to produce 209.7g fe? show your work. fe2o3 (s) + 3co (g) -> 3co2 (g) + 2fe (s) 2) solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. how many molecules of hydrogen gas are formed when 48.7 g of sodium are added to water? 2na + 2h2o -> 2naoh + h2 3) consider the following reaction: 2h2s (g) + 3o2 (g) -> 2so2 (g) + 2h2o (g) if o2 was the excess reagent, 8.3 mol of h2s were consumed, and 137.1 g of water were collected after the reaction has gone to completion, what is the percent yield of the reaction?show all work you.
