Transition metals is a rubbish topic, we need to learn a whole series of colour changes....

learning lists... my least favorite past time

To remember the colour of iron ions think about the seasons:

Fe(II): Second season - summer. Solution and hydroxide are both green.

Fe(III): Third season - autumn. Solution is yellow, and the precipitate is orange/brown (like the leaves in autumn)

Stupid, but it works :redface:

I keep calculating and re-calculating my UMS marks too.. I've still got 3 exams left though (argh). English synoptic, chemistry synoptic and chemistry AEA--why did I choose the AEA? It seems like utter insanity at the moment. I'm not going to do any work for it though, although I think will stop short of going out the night before the exam.

Heeeey Beibei :smile:

haven't seen you on here in aaages. How are your exams going?

Aired: that would work only according to AQA [Fe(H2O)6]3+ is violet...

On OCR it says that it's yellow in solution :confused:

(For trends & patterns anyway)

Yeah, the colours depend on the exam board and the book you look in, just learn yours and ignore me :P

OUchie. Where do you waitress?
Hmm, im looking for a job for part of the summer, im not really looking well as i dont want one :p:

But should probably get one for uni money.

This genius friend of mine (she's our age) has her own COMPANY supplying waitresses to catering companies, so it was a wedding party last night. Just been at a primary school reunion - weird to see how everyone turned out! Four of the five girls there are going to do medicine next year! :eek:

That iron-colours thing is genius! Right, off to revise in front of the football!

How do the UMS things work - from what i've read - if you got high a's you only need d's ???

Well you need 480/600 UMS to get an A

I had 372 after my January exam, and there are 210 UMS points available in the summer exams, so I need [ (480-372)/210 ] x 100 = 51% which is a D

What i hate is when books have different opinions! The Bible of AQA chemistry actually says Fe(III) is violet! (dont worry its only because it turns yellow when the h2o is hydrolysed)

LAST EXAM TOMOROW!!!!!

Basically, your raw mark in each module is scaled, depending on how well other people did and how hard the paper was, to give a UMS mark, usually out of 100, although it varies a bit to weight the different modules. Your AS part is out of 300 UMS, and your A2 part is another 300, so the overall grade depends on how many you get out of 600 - as Aired said, its 480 for an A, so if you get ~300 at AS, you can drop quite a lot of marks at A2 and still average out to an A.

The normal distribution

What about it? Do they assume marks are normally distributed around the average and then use percentiles of it for UMS?

As far as I know A levels aren't competitive i.e. you could get 99/100 but if everyone else got 100/100 you still wouldn't get an A, so I don't think they solely use the normal distribution when determining grades but I could be wrong.
