Sulfur dioxide (SO2 ) is a gas that is a polluant responsible for acid rain. It can be formed by the following reaction:
2H2S (g) + 3O2 (g) ? 2SO2 (g) +2 H2O (g)
What volume of 3.50M H2S is required to react with excess O2 to produce enough NH3 to fill a cylinder that is 50ft long and has a diameter of 13 ft at a pressure of 450 torr and 20°F?
