Answer the following True or False questions. H_2O, CO_2, CH_4, N_2O, O_3, CFCs

Question

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 arc 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

Explanation / Answer

a) The statement is TRUE, since the above listed gases acts as greenhouse gases and they trap heat as well

b) The statement is False, because the Cl take part in the reaction but also comes out as the product in the reaction

Cl is not taking part as a catalyst becomes it affects the reaction and determine the rate by the formation of ClO
