125 kg of coal contains about 7.0 % sulfur, by complete burning, the gases were circulated in a wet scrubber containing 25 kg of CaCO3 to convert SO2 evolved by complete burning to CaSO4. Is the amount of CaCO3 enough to absorb all SO2 or not? If not, how many molecules of SO2 will escape from the wet scrubber?
Halons are fluorocarbons that contain bromine, such asCBrF3. They are used extensively as foaming agents forfighting fires. Like CFCs, halons are very unreactive andultimately can diffuse into the stratosphere. (a) Based onthe data in Table , would you expect photodissociationof Br atoms to occur in the stratosphere? (b) Propose amechanism by which the presence of halons in the stratospherecould lead to the depletion of stratospheric ozone.

Loss of atmospheric ozone has led to an ozone “hole” overAntarctica. The process occurs in part by three consecutive reac-tions: (1) Chlorine atoms react with ozone (O₃) to form chlorinemonoxide and molecular oxygen. (2) Chlorine monoxide forms ClOOCl. (3) ClOOCl absorbs sunlight and breaks into chlorine atoms andmolecular oxygen.(a) Write a balanced equation for each step.(b) Write an overall balanced equation for the sequence.

Write the two reactions that contribute most significantly to ozone destruction in the stratosphere (non-catalyzed reactions).
13 The air that we breathe is actually a mixture of mostly the following gases- 78% N2, 21% O2, and (<1.0%) CO2 and H₂O and constitute about 99% of the air mixture on a poor air quality day. That remaining, approximate 1% of the air is associated with trace amounts of air and particle pollutants that can affect air quality, especially on hot, summer days. Groups that can be affected by poor air quality include those who have asthma, heart disease, and chronic obstructive pulmonary disease (COPD). If the total air pressure is 1.0 atm, what would be the partial pressure (atm) of O2 on a poor air quality day? atm. 480 words IX English (United States) (5 points) Focus F E
A proposed mechanism for ozone destruction in the late spring overnorthern latitudes in the lower stratosphere begins with the photochemicaldecomposition of ClONO2 to Cl and NO3, followed by photochemicaldecomposition of the latter to NO and O2. Deduce a catalytic ozonedestruction cycle, requiring no atomic oxygen, which incorporates thesereactions. What is the overall reaction?
