    Discovery Silicon
AI Thread Summary
Silicon was first identified by Lavoisier in 1787, but Berzelius is credited with its isolation in 1823. The commercial extraction of silicon involves heating silicon dioxide (SiO2) with coke in a blast furnace to remove impurities. Conducting a small-scale experiment at home is challenging due to the high temperatures required for SiO2 reduction. The discussion highlights that chemists historically aimed to decompose substances into simpler elements, driven by curiosity. For a report specifically on silicon, a focus on its extraction methods and historical context is essential.

what lead to the discovery of silicon

&

how is it extracted commercially & how can it be done at home aswell?

sry for bieng so blunt & so naive :p

i got this much so far. It was only identified in 1787 by a scientist Lavoisier. However, Berzelius was the first person to isolate silicon in 1823, and thus he is credited with its discovery (web1.caryacademy.org). the thing is i can't find out why he was doing what he was doing, i can't find anyinfo on that.

& i found my info about how it is extracted commercially, apparently they take out the impurities by heeting it with coke in a blast furnace. but i need a small scale experiment too which i can't find. i can only think of mixing it with sumthing to react with the oxygen & leave wat i need behind.
 


I am not sure if I understand the first question, as the only answer I am aware of is "curiosity". What I mean is that chemists were trying at the time to decompose every substance into what they called "simple substances" - what we today know as elements (note: don't treat nomenclature I am using too seriously, as I am translating from Polish). Berzelius was the first one to succeed in preparing pure silicon, but I don't remember reading about any special events that lead to that discovery.

Small scale & home experiment looks unlikely to me, you need high temperatures for SiO2 reduction. Does it have to be production of Si, or something else where Si compounds are involved will do as well?

lol that's good enough answer for me aswell.

& yes it has to specificcally be Silicon, as I am doing a report on it.
 
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...
