All this chemistry talk is giving me a headache.
The only thing I know of chemistry is the formula for water, H to O, written HIJKLMNO I believe.
You'd think they would give basic elements easier formulas. 
I think they give really long formulas just so chemists can act smart.
Anything more complicated than this is beyond me.  That is why I only got a B in Chemistry.
Kept me from being a road skolar and probably caused my profs to vote me "most likely to not secede".
I hate chemistry and everything that comes from it.  Thank God it has nothing to do with my life!
