CFCs are Chlorofluorocarbons. In other words they are halo-alkanes in which all H atoms have been replaced by Cl and Fl. They were made to replace ammonia in fridges and stuff(I think cos the ammonia was poisonous, no?). CFCs destroy O₃ as they form free radicals which "latch" onto O₃ and destroy it via catalysis. However once its done with its "prey" it can continue onwards destroying more O₃, which makes us vulnerable to medium intensity UV. And I'd write the eqn. for this but I forget

Cl• + O₃ → ClO• + O₂

ClO• + O• → Cl• + O₂



Gosh, I love those free radical thingies.

Thankies madamoiselle *bows*
I assume those dot thingamajigs denote a radical?

Yes. Yes indeed.

You're welcome.

Cl• + O₃ → ClO• + O₂

ClO• + O• → Cl• + O₂

for those radical thingys, there are many ways to write it. ie:

ClO + ClO --> Cl2O2

Cl2O2 + UV --> Cl2 + O2

Cl2 + 2O3 --> 2ClO + 2O2

does which ever way matters? cause they are all correct...
