- Suppose you are hired by the Environmental Protection Agency as an engineer to measure sulfur dioxide (SO2) emissions in a small industrial power plant. And suppose you analyze a gas sample and get 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 factory clerk the next day, and he insists that this analysis is erroneous and states that the fuel is natural gas, contains methane and ethane and does not contain sulfur. You ask if another fuel is used, and sometimes they say they use fuel as fuel, but at the time of analysis they say that this fuel is not used. However, your measurements show that the enterprise is using fuel at the time of measurement, and the responsible person accepts this later and accepts that they have made mistakes.a) Calculate the molar ratio of carbon / hydrogen in the fuel and use the result to prove that the fuel cannot be natural gas.b) Assuming that C, H and S are the elements present in the…Calculate the average atomic mass of Amazium, a newly discovered element (Amazium, symbol Az) which is determined by mass spectrometry to have two isotopes with the following masses and percent (%) composition (abundance) Show work.The organic salt tetrabutylammonium hexafluorophosphate is widely used as a non-aqueous electrolyte in electrochemistry.
