Assume that the wet limestone process requires 1 metric ton of calcium carbonate to remove +35.0% of the sulfur from 4 metric tons of coal containing +4.0% S. Assume that the sulfur product is calcium sulfate. Calculate the percentage of the limestone (calcium carbonate) converted to calcium sulfate.
At an altitude of 55.00 km, the average atmospheric temperature is essentially 0 degrees C. What is the average number of air molecules per cubic centimeter of air at this altitude? Hint: Solve the equation for the pressure as a function of height and temperature and from this use the ideal gas equation to calculate the volum
