Hi Lauren: I myself have been interested in nuclear chemistry and the making of nuclear weapons since August 1945, when I was eight years old. Early in that...
Hi Lauren: In previous messages, someone said that he/she was taking TNT as a heart drug. Pardon Lauren: The heart drug is trinitroglycerine. TNT is...
Hi Lauren: Unlike others so far, I ascribe your interest in nuclear chemistry and atomic weapons to intellectual curiosity. Intellectual curiosity has been my...
Hi Lauren: Most of the time, U-235 atoms decay by emitting alpha particles to yield thorium-231 with a half-life of 70 million years. This means is almost all...
Hi Lauren: More on intellectual curiosity. If an atom of U-235 fissions, it generates several neutrons. If there are many other atoms of U-235 nearby, they...
Hi Chaylin: It sounds like you want to finish your B.S. degree in chemistry and apply to vet school. Once out of vet school, you may want to consider a city or...
That is about right, except that the original matter of which Earth and the solar system was made of has an average age of about 4.5 x 10^9 years. This was...
In response to your message 8769 Most of the advice that is given about what a person should do with their life is bad advice. It takes a person's whole life...
A few years back, I came across the fact that Uranium is a pretty common metal, found in normal soil. It is the isotope used for nuclear fission that is hard...
hi, everybody . i m a new member of this group , u can say.i m working in a place where nucler energy is being used as a peacefull purpose. now a days we r...
First of all, I do not know why thoria pellets should change color. My best guess is that it is the coordination chemistry of thorium. Before sintering...
The chemistry of thorium is almost exclusively that of Th(IV), usually strongly coordinated because of the high charge on the Th++++ cation, with no unpaired d...
... ***CGS*** That was me. A brain fart. Sorry. You are absolutely right. Nitroglycerin is the heart medicine. And as an addendum to a previous post: yes,...
i need to determine how hot an octane flame is using heats of formation, heat capacities, information found on the NIST web book. the heat of combustion is...
shailendra, An important question is what do you mean by iu? Is this "international units?" If so, then this sounds like a medicine. You need to consult with...
I believe octane is C8H18. If I am wrong, you may correct my logic. Also you did not say if you are burning the octane in air, oxygen, or a halogen. Again if...
Pardon Pete: What you need are the thermodynamic parameters for 2,2,4- trimethylpentane. It is sometimes called "isooctane." Also, it is called "octane." It is...
I'm taking P-Chem right now, and I have a question. While calculating Standard Enthalpy changes, I noted that those for acid-base neutralizations of strong...
the balanced chemical equation for the problem is 2C8H18(g,298K) +25O2(g,298K)=18H20(g,298K) +16CO2(g,298K) this equation does not take nitrogen into effect....
Tim, Quick reply, as I just got out of the shower and have to get the household going. Call the HCl + NaOH rxn Reaction-1. The other is reaction-2. Subtract...
I have only been working as a chemist for a couple of years. I work at a pharma company and we are always looking for people. Perhaps our benifits package or ...
Nathan, Thanks for the quick response, but that's not quite what I was wondering. I realize that there is that -0.25 kJ/mol difference, the point is that was...
I look at this problem as stability of products versus stability of reactants. In both we have the same base NaOH accepts a proton to form Na+ and Water... Ok...
