there are two industrial methods of producing H2SO4 these are: 1.Contact process S + O2 -> SO2 (increase pressure, temperature for greater rxn rate,) SO2+1/2O -> SO3 (increase pressure, temperature for greater rxn rate) SO3 + H2O + H2SO4 -> 2 H2SO4 (increase pressure, temperature for greater rxn rate) 2.Lead Chamber process (not as easy to do) SO2 + 2NOHSO4 + 2H2O -> 3H2SO4 + 2NO (decrease pressure, increase temperature for greater rxn rate) NO + ½ O2 -> NO2 (increase pressure, temperature for greater rxn rate) NO2 + NO -> N2O3 (increase pressure for greater rxn rate) NO2 + 2H2SO4 -> 2NOHSO4 + H2O (increase pressure, temperature for greater rxn rate) SO2 + ½ O2 + H2O -> H2SO4 (increase pressure, temperature for greater rxn rate) for more information of exactly how these steps are performed, go here: http://basc.chem-eng.utoronto.ca/~basu/industrial_production.htm i remember reading somewhere a few months back that there is a catalyst involved in the former method. i did not see this when i found/devised the information shown above.

actually, according to cambridge, the melting point of SO3 is 16.8 celcius. that's pretty much irrelevant, however, considering that it all reacts immediately to form H2SO3 or H2SO4 depending on conditions inside the fruit

the NADH that is produced from glycolysis is taken to the mitochondrion where it undergoes oxidative phosphorylation which yields a maximum of 4 molecules of adenosine triphosphate

i assume longan is a fruit. since it is a fruit, i doubt it has SO2(g) in it. so...it has either H2SO3 or H2SO4 in it. really it depends on what other chemicals it is in contact with.

well, i suppose...it happens in 2 steps: SO2+H2O->H2SO3 then you can oxidize it by adding 15508kJ/mol^-1

again, this isn't what the thread is about; read the title: "Fahrenheit 9/11-What's your opinion? - Science Forums and Debate - Mozilla"

that's mostly irrelevant yeah, i saw the correlation. f451=temp at which books burn. f911=temp at which freedom "burns". it doesn't matter that he played off of bradbury's title; rather, what matters is the film itself.

it isn't terribly hard to oxidize the H2SO3, just so you know; only 7013 kJ/mol^-1 to get the sulfur to +5 and 8495 to get it to +6

come now, your logic goes beyond that. bush used the attacks to his financially and politically benefit; as you can see, the united states has become extremely authoritarian and bush has received kickbacks from corporations he awarded contracts to

please rephrase that

it's the least i could do

actually i messed that up; it wouldnt work in H2O but it would work in liquid NH3...perhaps in a solution of NH3 in an alcohol? my source: The Elements by John Emsley, page 104. cheesy name but it says: Oxidation states: Li^-1 (s^2) Li solutions in liquid ammonia

epsom salts. i understand how group 2 metals oxidize, but i was wondering if NH3 solutions have the same effects on group 2 ions as they do on group 1. also, i was wondering NH3 solutions would reduce aqueous group 1 ions since they reduce neutral group 1 metals.

actually, the united states has little control over afghanistan. remember that you can never control a population as long as they resist (think vietnam). also, the whole sarin thing is mostly irrelevant. first, is this a valid source? second, are they sure it's sarin? third, are they sure it's not the weapons rumsfeld sold them in 1984? fourth, was hussein ever going to use these?

i just remembered; NH3 solutions reduce alkali metals to form anions. would an NH3 solution be able to reduce Mg+2 in a solution of NH3 and MgSO4?

heh, 3%

SiO2 tends to form a hexagonal lattice structure. here is a picture: http://www.aml.arizona.edu/classes/mse222/1998/quartz/Quartzbs.gif and another: http://www.aml.arizona.edu/classes/mse222/1998/quartz/Image6.gif SiO2 is also known as quartz (a type of rock). it is a member of the trigonal trapezohedral class of the rhombohedral subsystem. in a large groups of SiO2, contrary to what the formula states as the bonding, each Si is bonded to 4 O atoms, and each O is bonded to 2 Si atoms. it forms this lattice structure because of intermolecular forces acting upon it. just as H2O "bonds" to other H2O in a sample of ice, SiO2 "bonds" to other SiO2 in a sample of quartz. Note: i use the term "bond" because it's really just van der waal's forces acting upon molecules. i dont consider these bonds, although many chemists do.

yeah, i am budullewraagh@hotmail.com feel free to add me

...yes...

also, can anybody here tell me the best way to isolate aqueous alkali and alkaline earth metals from their salts? of course, using electrochemistry is the best way, but i was wondering the most efficient ways to do so.

haha. aldrich sells beakers for $350+. no joke either. i have seen beakers as "cheap" as $15 on their site however. also, they will not sell me chemicals, for i am but an aspiring chemist without a degree or a proper lab. oh well

i have nothing against it. i support equal rights for all.

there is much need for reform

indeed
