1. at stp, how many liters of oxygen are required to react completely with 3.6 liters of hydrogen to form water? 2h2(g)+o2(g) -> 2h2o(g) a. 1.8 l b. 3.6 l c. 2.0 l d. 2.4 l 2. which conversion factor do you use first to calculate the number of grams of co2 produced by the reaction of 50.6 g of ch4 with o2? the equation for the complete combustion of methane is: ch4(g) +2o2(g) -> co2 + 2h2o(l) a. 1 mol ch4/ 16.0g ch4 b. 2 mol o2/1 mol co2 c. 16.0g ch4/1 mol co4 d. 44.0g co2/2 mol co2 3. which of the following statements is true about the following reaction? 3nahco3(aq) + c6h8)7(aq) -> 3co2(g) + 3h2o(s) + na3c6h5o7(aq) a. 22.4 l of co2(g) are produced for every liter of c6h8o7(aq) reacted. b. 1 mole of water is produced for every mole of carbon dioxide produced. c. 6.02 x 10^23 molecules of na3c6h5o7(aq) are produced for every mole of nahco3(aq) used. d. 54 g of water are produced for every mole of nahc)3(aq) produced.
