yea same I forgot it's 20%...also question 3 I chose the wrong answer.....maybe also I thnk I did PVA polymer wrong I chose both......wbu?
*It was about the diffusion diagram [C]
hey crystal, the repeated question was from this paper http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_s08_qp_1.pdf Q9it was a repeated question the answer was pq2.
exactly they dont polymeriseCheck this
And since a polymer is saturated then neither of them !It was asking about HOMOLOGUS SERIES not functional group..
Array, how can they exist in both alcohols and alkenes' homologous series? I told u alkenes are hydro carbons and alcohols cant polymerise so that monomer is neither an alcohol and neither an alkene
*It was about the diffusion diagram [C]
*.It was about seperating zinc carbonate from a mixture with water [ Filtration]
*It was nearly the same as this..The answer was P,Q,R,S
*.Element X has a proton number 18..Element Z has one more electron shell
*It was P2Q exactly the same as Sodium oxide ( Na2O)
*The point at which both an acid and salt are present was D..Since neutralization is over so all OH ions were neutralized a salt and excess acid are left
*There was a question about neutralization and endothermic it was only neutralixation.
*Oxidation reactive was V2O3---->V2O5
*Properties of titanium..All except low density..
*.The one about electroplating negative and graphite.
*.About iron and its extraction..Iron is harder to extract since it is more reactive.
*.The composition of the planet was Oxygen and carbondioxide.
*.The flammable gas was Hydrogen and metal was zinc.
*.There was a question about methane gas and its burning..It was methane-carbon monoxide-carbon dioxide.
*-Fertilizer was that with N,P,K
*-The gas which is denser than air and unreactive was D.
*-Oxygen was used to make steel.
*-The substance which neutralized the acidic air was lime.
*.Organic:
--The one which had the least carbon was this with boiling point up to 70.
--Fermentationof glucose.
-There was this one regarding functional groups.
--The one regarding PVA.
Check this
I dont have the QP when i have them i will post a thread..
Exactly..That's wat i said here many times...
It's a condeasation polymerization..Not an addition..
Condensation not addition...Condesation polymerization can't be included in p.1 since it is in the extended.
Thats why I am asking others to grade me XD....
Paper 1 doesn't include the extended syllabus..Check the sy file included.
Surely yes...cauz ur marks r approx like me....and many people said to me I'll take A*!Im not so sure myself
Chem:
Paper1:35/40
Paper3:68/80
Paper6:49/60
Phys:
Paper1:35/40
Paper3:65/80
Paper6:35/40
Do u think I will get an A* with these grades??
Thx
wat u mean with these marks.....?
