Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmQuestion 5 from which paper?(Original post by matthurry)
Anyone else abit nervous about question 5 in this? :/
What did everyone get in unit one? (Chem for life) ??? -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmi mean the last question, which is usually based on the isert pre-release (it's usually question 5)(Original post by EstebanK0)
Question 5 from which paper? -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmI got 10/12, 10/12, 10/12, 11/12, 12/12 i think(Original post by EstebanK0)
Done them all except Skill V (interpretation)
What marks did you get in them? What kind of questions came up in your Skill V?
skill 5 was all about ionic equations / half equations on halogens. LEARN OXIDISING POWER of halogens

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmAh. So we have info on all 3 shots for Skill V. Mine one will be about Group 2 elements, specifically Calcium. Thanks for the info man.(Original post by matthurry)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmdid you revieve the link to the F331 content if so could you somehow pass it onto me please thanks.(Original post by westarmy)
Can you please provide the links to these F331 content? Much appreciated -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmLooking at the specimen, which was also on PR stuff, id say it could ask to draw a monomer of the plastic and have a question asking to explain how the properties of this plastic make it sutible for what it us used for and also I would guess that it would ask for another use of the plastic. Most of the time, if not all, there is a long 6/5 mark question. Guessing here, it will probably ask about the different density polymers, or it could ask about the formation of polyethene.(Original post by puddinboy)
Has anyone got any possible questions that may come up regarding the advance notice on 'Plastic Fantastic'????
Hope that may give an idea

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmThese are ideas that I had about potential questions too(Original post by david2457)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pm
at the bottom of page 2 there is a reaction involving a radical and ethene, does anyone know what kind of reaction this is?
At first i thought that its homolytic fission but i am not sure now.
Now i am thinking it is electrophilic addition. does anyone know?Last edited by thegreenchildren; 28-04-2012 at 19:15. -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmIt's radical polymerisation - which is not on the syllabus so you aren't supposed to already know all the details: http://en.wikipedia.org/wiki/Radical_polymerization(Original post by thegreenchildren)

ahhh ok. do you think they are likely to ask a question about this?
Also has your teacher been through the article with you? Mine hasn't !
-
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmAren't the uses of polyethene already in the article? do you think we would have to extract them from there? Also by properties do you mean flexible?(Original post by david2457)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmNot sure what they will ask, but do revise the topic of radicals and the topic of polymerisation.(Original post by thegreenchildren)

I'm not a student, but I think it's quite normal for the teachers to not go through it with you.
Best advice i can give is print off the syllabus and go through it with a fine tooth comb to check you know everything on there and then you should be fine.

We have been tought F331 & F332 so badly. The teachers have just skimmed over every topic, and we still have one or two more things to learn!!.
So yeah, you could say I'm bricking it for the F332 exam especially. Any tips on how to revise all the content, because there certainly is a lot of it! I suppose I'll be doing a lot of past papers as well! -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmsame, in my last few chem lessons, our teacher has made us play games using memory cards to remember the different alcohols (ethanol, methanol etc.)(Original post by George_)

anyway, i would say memorise mark schemes because the same questions come up in nearly every exam paper. It really helps when it comes to the 6 mark questions. -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmThanks! I'll do that(Original post by thegreenchildren)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmYeah most likley with reference to the article, however from doing past papers a good amount of the 20 marks you can do with your own chemical knowledge(Original post by thegreenchildren)
