a couple of fairly random questions
« on: February 08, 2007, 09:18:53 PM »
ok,

1. carbonic acid: can some body tell me about this stuff?  why is it so "unstable" at pure forms?
what happens when it gets too unstable? what does it decompose to? about how much is in your coke?(percentage-wise) whats the ph supposed to be? and is it liquid or solid at room temp?

2.ya i know i asked this, i think, but is there a good website or place in the usa, other than ebay or united nuclear where you can get wide variety of chemicals and/or isotopes without being assosiated with a company?


3. i think i have molecular engineering and chemical synthesis mixed up, but is there 1 or a very few couple of ways to synthesis most all chemicals? or is there different ways of doing that for just about all compounds?


4. i know tungsten and carbon have the highest melting points,, but is there a simple chemical compound that goes farther, mabye tungsten carbide, or my dad has talked about aluminum oxide? i would like to know the melting points of these two specificly so we can clear things up

i'm sorry if those questions are bad but i'm sorry just trying to get a grasp on this high level chemistry and stuff.

1)
http://en.wikipedia.org/wiki/Carbonic_acid

3)
For most chemicals there are many ways. It all depends on what you are starting with, and what you are using it for. I.E. how pure do you need it. Also, if you are making small amounts for laboratory work, or large amounts for commercial/industrial use.


4)
W (tungsten) melting point, 3433oC
http://en.wikipedia.org/wiki/Tungsten
Carbon forms many allotrope's ( http://en.wikipedia.org/wiki/Allotrope) and therefor the different "types" of carbon have different physical and chemical properties.
Aluminum Oxide (http://en.wikipedia.org/wiki/Aluminium_oxide) has a melting point of 2054oC.
Tungsten Carbide (http://en.wikipedia.org/wiki/Tungsten_carbide) has a melting point of 2870oC

I am very succinct, so do not get offended. But you really should learn to look/research for the information/knowledge you need first. It is one of the most important skills you can develop, and the internet makes it quite easy now. When you have specific question/want clarification ask here.
