I don't know... I mean looking at the question after that I changed my answer to H2SO4. SO3 does not have environmental consequences on its own without first turning into H2SO4. Donno, I could be wrong.it was so3 , it forms when no2 and so2 react when so3 is formed then h2so4 forms
The ring structure opens up, actually (doesn't look like it in your structure though; sorry if that's what you meant). It'd be simply HO₂C(CH₂)₄CO₂H/ \
| COOH
| COOH the cyclohexane will look like this in q4 last part

It was -49mayb yea coz almost all d ppl at my centre are definitely goin to lose 10 marks here n dere for sure.....was the enthalpy value cumin in -47 or someting?buh it sure was exothermic reaction....most of d ppl evn went wrong on d 2nd question based on moles...
lookin all over the internet just to know the reaction of HBr with ethene..cant freakin find the colour change in the internet ! from where do CIE get these stuff Oo
orange or brown? OoIt was from orange to colourless
orange or brown? Oo
pprs goneeeeeeeee lets jst 4get abt it nowI don't know... I mean looking at the question after that I changed my answer to H2SO4. SO3 does not have environmental consequences on its own without first turning into H2SO4. Donno, I could be wrong.
yes :3GUYS, what was for the question with the equlibrium it was Exothermic, yeah?
for 3 it reacts with ethene....addition takes place...and bromo ethene is produced....where did u get thaat red brown gas?SuP. IM back
and these are some of my answer for some questions
1) i wrote SO3
2) the enthalphy change is -49
3) the colour of HBr is colourless and when reacted Br2 is produced so it changes to reddish brown
4) the percentage of purity is 90.8
5) and the cyclic one when reacted with hot conc. KMnO4 ..its... HOOCCH2CH2CH2CH2COOH
and gud luck in today's bio practical
Really ?????!!!!!!for 3 it reacts with ethene....addition takes place...and bromo ethene is produced....where did u get thaat red brown gas?
3In the last question did the compund x had 2 carbons or 3 carbons
