no dudehey guys, do we need study organic chemistry for paper 6 !! please answer asap!!

http://www.gcsescience.com/o55.htmAnybody having good notes of polymerisation ?? i see all the p3's of chem have questions frm polymers =\
is that even there in our course??Explain why the combustion of waste crop material should not alter the percentage
of carbon dioxide in the atmosphere.
i copied it from a past paper .. o/n 2010 ..is that even there in our course??
Because the crops photosynthesized while they were alive, therefore the CO2 that goes into the atmosphere when they are burnt only cancels out the CO2 the crops took out via photosynthesis.Explain why the combustion of waste crop material should not alter the percentage
of carbon dioxide in the atmosphere.
They have told above that the solid V is insoluble that means when the mixture is filtered it will be as a residue.http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_s11_qp_62.pdf
Question 5, I totally get scared when I see this type of questions, and they always come.
I couldn't figure out whats the solid, etc.
So could you tell me what shall I study for this question? I have studied Testing for anions/cations (sulfate ions/carbonate ions/nitrate ions), Identifying gasses, Metal ions, etc..
Does anyone have any physics notes?
Thanks Mate!http://www.xtremepapers.com/community/threads/all-notes-o-level-0r-igcse-a-level.4866/ go to the physics portion!!
better to write no change or insoluble in excess, =]Quick question: if I'm asked to write observations when excess aqueous sodium hydroxide is added to an iron (III) salt solution, should I say 'ppt. is insoluble in excess' or 'no change in excess'? The mark scheme of O/N 2003 says 'no change in excess'...
http://boomeria.org/chemlectures/qual/qualnotes.pdf i think this might help try it .. if not, just temme =]There was a questions about appearance of some compounds lets say Potassium Iodide.
Since I haven't done much practicals, is there any list that contains useful paper 6 compound colors?
If anybody has any doubt in chemistry paper 6 , inbox me or tag me here,
Best of luck everybody =]
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
