chemistry?!?
answer the following briefly.
a. where and when did
chemistry begin?
b. what are the related
sciences that make use of
chemistry?
c. where can a chemist work
after graduation?
10 pts. for the best answer.

a. The chinese have been experimenting with salt peter mixtures and using them to develope various "gun powders" since about the 9th century. I'd call that chemistry. The best place to learn about it would be here. http://en.wikipedia.org/wiki/C hemistry b. Most sciences relate and make use of it but especially astronomy, physics, material science, biology, and geology. I would suggest that physics is less so, and that biology, and material sciences depend on it more so than the others. c. Analytical labs, Environmental testing and field work, Engineering positions, material science work, food industry work, pharmaceutical labs, crime scence investigation(tough to get a job here, few positions), any production facilities like manufacturers of hair spray and shaving cream all need chemists. The money is in the pharmaceutical and engineering positions, run away from environmental and analytical as they are horribly underpaid. |

What chemistry principles I understand that a broad and
intricate knowledge of the
basics are important, but I'm
not at all sure what basics I
should start with. My idea was
to read through a general
chemistry textbook, but it's
turning out to be somewhat
overwhelming. I'm looking to
pursue a career in organic
chemistry (organic chemistry
textbooks are too specific and
don't really allow for a broad
understanding of the subject
matter).
I'm already taking chemistry
courses at a university; the
aim of this question, to
restate, is to help me figure
out where I should be
concentrating in my spare
time.

I am an inorganic chemist. I have a colleague who is a biological chemist. I once asked him, "What, besides biological chemistry, do you think is most important for your students to understand?" His answer? Physical chemistry. Besides inorganic chemistry, that's my answer too. Thermodynamics, kinetics, bonding. Not so much at the level of being able to derive thermodynamic relationships with partial derivatives, but having a sort of honors-level freshman chemistry understanding. Know order-of-magnitude numbers! How strong are typical bonds? How much energy is kT (or RT on a per mole basis). What is the energy range of visible light? Infrared radiation? NMR frequencies? What are typical bond lengths? etc... You'd be amazed at how important these kinds of things are to chemists of all kinds - organic, inorganic, or analytical. |

What are the options if you What are the options if you
pass the chemistry class but
failed the NY regents?
I failed the chemistry regents
and I heard from a senior that
if you pass the class, you
don't have to take the
regents. Is that true? What
diploma would you get? Is it
better for me to take the
regents over again? Are there
any other ways to gain back a
advanced regents diploma since
I failed the chemistry
regents?
Only serious answers please.

If they offer the chem regents over the summer, you can retake then and not have to worry about it anymore if you pass this time. |

A sample of the drug terfenadine crystallised from ethanol has a melting point of 154 oC, whereas a sample of terfenadine crystallised from acetone has a melting point of 149 oC. When the aqueous solubility of the two recrystallised samples are compared, they are also found to differ significantly. Give a reasoned argument to account for the observed differences in the melting point and solubility.
