Here is just one question on a review for Friday's chemistry test:
If boron hydride (B4H10) is treated with pure oxygen, the following equation occurs:
2B4H10 + 11 O2 --> 4 B2H3 + H2O
If a 0.05g sample of the boronhydride burns completely in O2, what will be the pressure of the gaseous water in a 4.25 L flask at 30.0 oC ?

Yeah...I got the 'right' answer, which was 0.27 atmospheres, but, I know for a fact that it was wrong, because you didnt' even factor in the temperature...so...

HAHA, at my school thats what all the stupid freshmen take ;D Haha. At my school, that's what all the science rejects take. :X It's for people who suck at the main sciences (physics, chem, biology) and take that instead. Btw, what part of chemistry is that problem from?

That was from the chapter on gases. Pressure, volume, temperature, moles and what not.
I'm so pissed. I failed that test. I studied hours last night, and then fail.
It's not all my fault though: the teacher is so retarded, the very first problem on the test was not do-able because she didn't give us enough information.
If 2.0 of gas is emersed into 0.01 degree Celcius water, what is the new pressure?
1) The STP of gas is at 0 degree Celcuis. So, it went up 0.01 degree. 2) We weren't told if the pressure remained the same.
Conclusion: My teacher is inept at teaching, and should be banned from LIFE for not having a competent brain.

I love biology.
I think it is soooooooooooooooooooooooooooooooo much easier than chemistry...no matter what anybody tells you, chemistry is just physics (physics = math) in disguise.
