Identify at least two pollutants that destroy the ozone layer. discuss the origination of these pollutants and a plan for reduction.

The two pollutants that destroys the ozone layer are CFC (Chlorofluorocarbons) and Methyl bromide. When the sun rays hit these molecules, they releases chlorine and bromine into the atmosphere. The chlorine and bromine reacts with the ozone present in the stratosphere and thus results in the depletion.

The origination of these pollutants are refrigerators, Air conditioners and aerosol cans.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

fe 55.85 g/mol and h2o 18.02 g/mol.
