Answer the following True or False questions. H_2O, CO_2, CH_4, N_2O, O_3, CFCs are molecules are considered greenhouse gases, What they have in common is that they are infrared active and therefore can effectively trap heat True False The depletion of ozone in the stratosphere has been linked to the generation of Cl radical from clorofluorocarbides caused by UV light. Cl radical participate in the following reactions with a catalytic role because it is regenerated at the end of the cycle: Cl + O_3 rightarrow ClO + O_2 ClO + O rightarrow Cl + O_2 O_3 + O rightarrow 2O_2 True False
