AI Thread Summary
Beryllium was discovered in 1798 by Louis-Nicolas Vauquelin, who identified it in beryl and emerald. Historically, Beryllium compounds were utilized in fluorescent lighting tubes until 1949, showcasing its importance in early lighting technology. Additionally, Beryllium has been used in aerospace applications due to its lightweight and strong properties. The element is also significant in nuclear applications, particularly as a neutron moderator. Understanding these aspects can enhance the depth of an assignment on Beryllium.

Chemistry question..pretty urgent..

Hi, I am doing an element assigment and I was assigned to do Beryllium. Does anyone know how to get overly-detailed information on how Beryllium was discovered and its historical usages? I got everything except those 2 aspects of the assignment.. I only know that Beryllium compounds were used in fluorescent lighting tubes until 1949.

Thanks in advance..=)

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
