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 is the difference between what is the difference between
organic chemistry, and normal
chemistry?
and do i need to learn normal
chemistry first in order to
learn organic chemistry?

normal chemistry can also be referred to as nonorganic chemistry. The title 'organic' refers to chemicals existing in and derived from plants and animals. You can think of organic chemistry as referring to anything that is alive. That being said, organic chemistry is then paramount to any type of science that deals with plants or animals. This means it is very important if you want to go into medicine, pharmacy, enviornmental science, or anything else that deals with plants and animals. Organic chemistry is also one of the most challenging forms of chemistry; it indroduces many new concepts that can be difficult to grasp. I heard a rumor while I was in school that organic chemistry is the most commonly failed college course. I know that it was difficult for many of the students in my class. To answer your second question, a solid background in normal (inorganic) chemistry is important for learning O chem, kinda like learning to add and subtract is important for learning multiplication and division. They arent quite the same thing, but they are related, and inorganic chemistry is much easier to learn. So while you could learn to multiply and divide without knowing how to add and subtract, that knowledge makes your life much easier. |

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.
