Working as a summer student for the ministry of natural resources you are responsible for testing the water in a creek near an industrial site for the presence of
the toxic metal ions lead (II) and mercury (II) in the water. Design an experiment to
sequentially test for the presence of lead (II) and mercury ions as well as the non-toxic
magnesium ion. Assume the water sample does not include any other interfering ions.
Show the net ionic equations for the precipitation reactions that might occur.

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.
