oh alrighty then, then im gonna start with the contact process first..
1)first,sulphur is allowed to react with oxygen to form sulphur dioxied(its an oxidation reaction as oxygen is taken)
2)then this sulphur dioxide is allowed to react with oxugen again to make sulphur trioxide (SO
3). this reaction has some rquirements which are : catalyst: vanadium pentoxide or vanadium (v) oxide(V
2O
5),temperature : 450
oC, and its at atmospheric preassure (but is unspecified on what ammount of atmospheric preassure).
3) sulphuric acid can esily made by just reacting water with sulphur trioxide directly, however this reaction is vilent and produces thick mist like smoke tht can cause u to choke, so to avoid this problem, the sulphur trioxide is dissolved in some sulphuric acid (labratory prepared one) to give oleum (H
2S
2O
7)
4) then correct amount of water is added to this oleum to produce sulphuric acid of the required concentration.
and thts all with the contact process, hope this helped, then ill try to answer the moles stuff later, but the required formulas needed for moles are here:
to find the number of mole with mass and Mr and Ar.
Moles=mass/Ar or Mr
to find number moles with volume
moles= volume in dm3 / 24
if the volume was in cm3 then devide it by 10000. (to do any calculations with volume in it, the volume must be in dm3)
volume in dm3= volume in cm3/1000
to find number of moles interms of volume in dm3 and concentration (unit=(v/dm3))
moles= volume in dm3 x concentration
