A particular coal sample contains 2.32% S. When the coal is burned, the sulfur is converted to sulfur dioxide gas. What volume (L) of SO2(g), measured at 25°C and 749 mmHg, is produced by burning 20 * 106 lb of this coal? (1 lb - 454 g)

Enter your answer in the provided box. The SO2 present in air is mainly responsible for the phenomenon of acid rain. The concentration of SO2 can be determined by titrating against a standard permanganate solution as follows: 58O2 + 2MnO4 + 2H20 - 55042- + 2Mn2+ + 4H Calculate the number of grams of So, in a sample of air if 3.50 mL of 0.00700 M KMnO4 solution are required for the titration.

Trace amounts of sulfur (S) in coal are burned in the presence of diatomic oxygen (O2) to form sulfur dioxide (SO2). Determine the minimum mass of oxygen required in the reactants and the mass of sulfur dioxide in the products when 5 kg of sulfur is burned. Use data from the tables. The minimum mass of oxygen required in the reactants is ------------------------ kg. The mass of sulfur dioxide in the products is -------------------- kg.

Enter your answer in the provided box. The formation of SO3 from SO2 and O2 is an intermediate step in the manufacture of sulfuric acid, and it is also responsible for the acid rain phenomenon. The equilibrium constant KP for the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g) is 0.13 at 803°C. In one experiment, 2.00 mol SO2 and 2.00 mol O2 were initially present in a flask. What must be the total pressure at equilibrium in order to have an...

1) A particular coal contains 2.55% sulfur by mass. When the coal is burned, it produces sulfur dioxide emissions, which combine with rainwater to produce sulfuric acid. Determine how much sulfuric acid (in metric tons) is produced by the combustion of 2.0 metric ton of this 15pts coal. 2) A box contains equal amounts of helium, argon, and krypton at 25C. Describe the masses, average velocities, and average kinetic energy of the three kinds of gas in...
