Emissions of sulfur dioxide by industry set off chemical changes in the atmosphere that result in "acid rain". the acidity of liquids is measured by ph on a scale of 0 to 14. distilled water has ph 7.0, and lower ph values indicate acidity. normal rain is somewhat acidic, so "acid rain" is sometimes defined as rainfall with a ph below 5.0. the ph of rain at one location varies among rainy days according to a normal distribution with mean 5.43 and standard deviations 0.54. what proportion of rainy days have rainfall with ph below 5.0?

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
