Question

Answer the following True 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 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 CI radical from clorofluorocarbides caused by UV light. CI radical participate in the following reactions with a catalytic role because it is regenerated at the end of the cycle: True False

Answer 1

Green house gases absorb infra red radiation and then re-emitted in all directions. This casues the temperature of earth to rise. So there is no trapping of IR. ( Flase)

2.ClO ( formed from Cl+O3--->ClO+ O2) is a highly reactive gas that is involved in catalytic ozone destruction cycles throughout the stratosphere
