man, chemistry. my most hated class. i think that is the only class i have ever taken that i really didnt understand.
im not much of a math and science guy, im more of the english and history type. stoichiometry makes me want to bang my head against a desk
if a quiz is quizzical, then what's a test?

yea for real...sometimes I think chemistry is just completely made up.

Don't worry about it. Once you're out of the class you'll forget it all anyway. I took it last year, was an A+ student, and really knew everything in the class, but the only thing I remember now is Avogardo's number.

well thank you.  It helped a little but what I'm looking for is the chemical aspect. like "first there was sulfur and then this was replaced by phosphorus in the 1820's"
get what I mean? |

describe the atomic orbitals involved in the bonding of a water molecule. explain how the orbital structure and molecular bond polarity of the water molecule dictates the physical and chemical properties of water. i did chemistry A level last year and failed LOL. But seriously i knew wat atomic orbitals were and now i just cant remember any of it

I feel oh so dumb... especially since even Rzad knows this, and I don't

Ugh.. I'm still in Chemistry, I can hardly stand it... Bio would be worse though... It seems to me like a graph of how much of your mind you use during the three sciences goes like this:
Bio < Chemistry < Physics I swear, physics is the shit, although I don't think we do enough theory, in Chemistry though I'm just off the wall, I had a water fight with another bench once... and I'm still getting 92. Life is good...   www.mission-control.tumblr.com |

Physics is a very interesting class (especially AP), but my teacher is the biggest douchebag on the face of the earth, so I am not having a lot of fun in it right now.

reminds me of a saying tho i dont remember the exact saying i think it was something like:
biologists look to chemists for answers. chemists look to physicists for answers. physicists look to mathematicians for answers. mathematicians are all knowing all powerful (no i made that last part up  )

Close. It's:
Biologists think they are biochemists, Biochemists think they are Physical Chemists, Physical Chemists think they are Physicists, Physicists think they are Gods, And God thinks he is a Mathematician. www.mission-control.tumblr.com |

ok well I finished the paper...took 3 hours of research to get enough info. our chemistry teacher is so cool tho...i swear this dude knows EVERYTHING!
we know he played for the dallas cowboys as a kicker its a thing we made up but we know he did play football somewhere..he's pretty old now tho..
he's still a genius and strong enough to flip over a desk with a kid in it still I'm in the honors class so he goes faster with us and teaches us more and doesn;t really mind when we talk but for all of the other classes he's like "SHUT THE F*^& UP!" cause he hates them lol
but U can say ur in AP physics and all but the classes may be the same, but the teacher is prbably easier from one school to another...and I beleieve thats why they have the SAT's so colleges can tell which kids are "smart" and which ones just had easy classes. get what i mean? |
