4.1 (Mt. You have been sent by the Environmental Protection Agency to measure SO2 emissions from a small industrial power plant. You withdraw and analyze a gas sample from the boiler stack and obtain the following composition: 75.66% N2, 10.24% CO2, 8.27% H2O,5.75% O2. and 0.0825% SO2. You show these figures to the plant superintendent next day. and she insists they must be wrong, since the fuel was a natural gas containing methane and ethane, and no sulfur. You ask if they ever bum another fuel, and the superintendent replies that they sometimes use a fuel oil but the plant log shows that they were not doing so when the measurements were made. You do some calculations and prove that the oil and not the gas must have been the fuel; the superintendent checks further and discovers that the plant log is in error and you are right.
- Calculate the mole ratio of carbon to hydrogen in the fuel, and use the result to prove that the fuel could not have been the natural gas.

- 1. [15] Atmospheric pressure (P) decreases with increasing altitude (h) based on the following exponential function (with e as the base): P = Pº 1 exp Mgh RT where Pº=1 atm at h=0 (sea level) and T'is the average temperature of the atmosphere, M the molar mass of air (29 g mol-¹), and g the standard gravity.

It is quit soluble in water, so to isolate it the solution has to be evaporated to dryness. This drives off the volatile HCl, but the residual solid has to be heated to a little over 200 celsius to drive off the water. In one experiment, 25.0 g of AlCl3 were mixed with 30.0 g of H2SO4. Eventually, 28.46 g of pure Al2(SO4)3 were isolated. Calculate the percentage yield. 2.
