**Determination of Stoichiometric Coefficients****Prelab Exercise for "Determination of Stoichiometric Coefficients" Experiment**1. A primary cause of acid rain is the burning of coal having a high content of sulfur. Burning (oxidation) of the sulfur produces sulfur dioxide which in turn is further oxidized to sulfur trioxide in air. When the sulfur trioxide combines with water droplets, sulfuric acid is formed. a) Write a balanced equation for this last reaction. b) Suppose a solution of sulfuric acid was prepared according to the reaction above. If the concentration of sulfuric acid is 0.0500 M, what would the concentration of the solution be if it is expressed as M of SO₃? (HINT: Think about the stoichiometry of the reaction.)2. Scientists will often use different units to express concentration. For example, the concentration of a solution might be expressed as mg of solute per liter of solution, mg/L. Assuming you had a solution of 0.0500 M H₂SO₄, determine the concentration of SO₃ in mg/L. (HINT: Look at your answer for question 1b for help.)3. Suppose you had a solution of H₃AsO₄, a triprotic acid, having the same concentration as that of the sulfuric acid in the previous experiment. If you were to titrate 10.00 mL of the H₃AsO₄ using the same NaOH you used in this experiment, would you expect that it would take more, less, or approximately the same volume of NaOH (compared to the H₂SO₄ trials) to completely neutralize the acid? Explain.
