Edexcel A2 Chemistry Unit 5 ~ 22nd January 2013

If some of us had remembered that nitrogen was a diatomic molecule, the question would have been a piece of cake :mad2:

Those examiners know exactly where to trip up the candidates, can't blame them though for making us think twice about the fact that Nitrogen is diatomic!

Didn't know my name was mention :colondollar:

The chemistry exam threads (jan and jun) were great preparation and it helped acknowledge my weaknesses in the spec :yep:

Ye, I am doing 4 and 5 again, need 73% over both mods for the A. I finished all unit 4 organic today, enjoyed it, Just hate the maths so much. Unit 5 was again also more enjoyable this time, I have learnt it all essentialy, but I just hate chem overall really, so boring and tough to concentrate on.

What marks did you get in it? And are you on a deffered entry, or didnt meet your offer?

Hey guys. I was predicted an A* in chem and ended up getting a B because i got a D in this exam! Anyway, this summarizes most of the course apart from complex colours:

How has it been going James :biggrin:

I have done the whole entropy and unit 4 organic files you sent me, I feel drowsy :s-smilie:

I will maybe start redox tomorrow, and then alternate between that and then maybe rates, and then back to transition.

From June 2011 paper Q17 (iv)

The diluted sample was made by adding 10cm³ of the drink to 90cm³ distilled water, a total of 100cm³ and then using 5cm³ of this, is this correct?

Concentration of ethanol in 5.00 cm³ of the diluted sample = 0.197 moldm^-3

So why is the concentration of the undiluted sample NOT 0.197moldm^-3 x 20 ?

If 5cm³ is taken from 100cm³ ?

That's what I mean by failure too XD Lots of people here are like "I failed.. I got a B :frown:

" and I completely admire people for having high ambitions and for being marvellously intelligent, fair play to them. But then there's people like me that worked their bums off and got under 40% in Unit 2 :biggrin:

But my attitude has changed, I've taken the challenge in my stride and I'm ready to resit it in January. My Unit 4 mocks have been alright too, so the road only goes upwards from here guys! Good luck for your Unit 5's, I'll be doing this for the first time in June. And I guess the last time, because of the removal of January resits.
