Freon−12 (cf2cl2), widely used as a refrigerant and aerosol propellant, is a dangerous air pollutant. in the troposphere, it traps heat 25 times as effectively as co2, and in the stratosphere, it participates in the breakdown of ozone. freon−12 is prepared industrially by reaction of gaseous carbon tetrachloride with hydrogen fluoride. hydrogen chloride gas also forms. how many grams of carbon tetrachloride are required for the production of 28.5 dm3 of freon−12 at 21°c and 1.62 atm?
