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 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: CI + O_3 rightarrow CIO + O_2 CIO + O rightarrow CI + O_2 O_3 + O rightarrow 2O_2 True False

Explanation / Answer

Q7

The argument is true, not only they will increase Temperature due to their formation (i.e. CO2 and H2O are formed when combustion is done) But they will also "retain" and "Trap" energy from the sun and atmosphere.

The heat from the sun will not be able to go to outer space since the chemicals will retain their heat

Q8

The reaction is correct,

The CFCs are hazardous due to their Cl* radical formation

they attack O3 molecules, and are essentially catalyst, so they will NOT stop since they will not consume

the overal reacition is O3 + O = 2O2
