2. sulfur dioxide gas (so2) reacts with excess oxygen gas (o2) and excess liquid water (h2o) to form liquid sulfuric acid (h2so4) in the unbalanced equation below: so2 + o2 + h2o  h2so4 in the laboratory, a chemist carries out this reaction at stp with 67.2 l of sulfur dioxide (so2). how many liters of h2so4 did the chemist produce? 1 mole of any gas = 22.4 l of that same gas at stp • part a: write a balanced equation for the reaction. • part b: calculate the number of liters of h2so4 produced.
