A typical coal-fired electric generating plant will burn about 3
metric tons of coal per hour.
Most of the coal burned in the United States contains 1 to 4 % by
weight sulfur in the form of pyrite, which is oxidized as the coal
burns:
4FeS2(s) + 11 O2 (g)--------> (Fe2O3(s) + 8 SO2(g)
Once in the atmosphere, the SO2 is oxidized to
SO3, which then reacts with water in the atmosphere to
form sulfuric acid:
SO3(g) + H2O(l) ----------> H2SO4(aq)
If 71.0 metric tons of coal that contains
2.69 % by weight S is burned and all of the
sulfuric acid that is formed rains down into a pond of dimensions
384 m x 233 m x
5.96 m, what is the pH of the pond? (OK to assume
2 mol H3O+ per mole
H2SO4.)
Hint: 1 metric ton = 1000 kg

A typical coal-fired power plant burns 290 metric tons of coal every hour to generate 800 MW of electricity. 1 metric ton= 1000 kg. The density of coal is 1500 kg/m3 and its heat of combustion is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electrical energy. Part A)Suppose the coal is piled up in a 8.0 m × 11 m...
A typical coal-fired power plant burns 320 metric tons of coal every hour to generate 2.6×106 MJ of electricity. 1 metric ton = 1000 kg; 1 metric ton of coal has a volume of 1.5 m3. The heat of combustion is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electrical energy. 1.
