Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmYeah, our class suck, most people got D/E/U in F331 in Jan. We've done PR before Atmosphere for some reason. ES has been done, yes. I just self-studied the content myself.(Original post by EstebanK0)
Seriously? Have you guys done Polymer Revolution and Elements from the Sea?
How much revision have you done Zhy?
I have done all the papers from Jan 2002 to June 2006 (old spec), only about 13 more papers to go! -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmThey are all in the specification which you can find on the ocr website.(Original post by puddinboy)
Can someone please tell me all the reagents and conditions for all the reactions in our spec that we need to know!!!! Would be a massive help!

I am in the same situation. All my class got U's in January.

Same with my class. Only one person got an A. I got a C but will be retaking next year so I can focus more time on F332.(Original post by Zhy)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmA lot of it just seems like Polymer Revolution content. Unfortunately, I haven't had time to throughly go through it. It'd be great if someone amazing (looking at you Zhy(Original post by megank)
Anyone done any work on the pre release?? or predicted any possible questions??
) could annotate and upload it here for us to thrive on.

Revise like unit 1. look at mark schemes and learn the generic answeres they look for often (definitions of dynamic equilibrium I have seen about 4 times) similarly points and on the long answers give every detail you can so not to miss the mark. Its as easy to lose easy marks as it is to gain them and every mark makes a difference. Anyone know how they did in their practical assessments?

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmI've been through it. Definately going to have a q. related to environmental impacts or the differences between LDPE and the HDPE perhaps linked to the branching idea. The free radical mechanism seems to be stressed so expect something along those lines too. Spectroscopy from unit 1 may make a reappearance too. Reckon that nearly all the polymer questions will come up on he last question which means elements from the sea and atmosphere needs to be revised reallly well for the other 80 marks!(Original post by EstebanK0)

Has anyone got/made/been given any help sheets, possible questions, explanations by their teacher etc on the Advance Notice?
Last year there were some really good documents uploaded here and some of the main points came up in the exam in nearly the exact same wording aha.
If anyone has anything similar this year it would be greatly appreciated
Love doing Chemistry re-sits

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmCould you post those "fill in the blanks" type answers like you did with F331? Those were very helpful.(Original post by Zhy)
I did all the past papers, now got nothing to do.
Better start making pre-release questions, I suppose. Anyone got any? -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmHmm, I'm not sure if there are any questions like that in F332 though. For example, the ozone depleting questions or the global warming ones are easy to score full marks in if you just say the same thing every time. I've got a comprehensive list of everything you should say, but no fill in the blank-type answers... sorry.(Original post by EstebanK0)

Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmWould you be able to send me/upload the list onto here? Would be much greatful.(Original post by Zhy)

Well, for the global warming questions (how CO2 causes Earth to heat up) I always say this:
-The Sun emits high-energy UV radiation, warming the Earth
-Earth absorbs UV and emits IR
-IR is absorbed by CO2 molecules, causing their bonds to vibrate more
-This vibrational energy is transferred to kinetic energy
-Energy is re-emitted in all directions causing a rise in atmospheric temp
-A higher conc. of CO2 mean more IR is absorbed so more kinetic energy, so greater heating effect on the Earth
This has always scored me full marks on those questions. The ones about CFCs are different though, do not say the above for those questions. -
Re: OCR AS Salters Chemistry F332 - Wednesday 23rd May 2012 1:30pmYou just need to be able to know how to read them -- just look at the peaks and match them to number ranges in the table. You also need to know that the fingerprint region is below 1500cm-1 which acts as a unique identifier for the chemical (which can then be looked up in a database). You should know that different bonds vibrate at specific frequencies, and talk about vibrational energy levels (they're discrete, bla bla) as the reason.(Original post by EstebanK0)
What do we need to know about infrared spec? I'm not very good with that.
