yes you should get the mark Mass Spectroscopy was also correct :P

Technically, that is mass spectrometry... be careful!

[James_01]

Nooooo!!! Stop asking if you would get the mark. If its not on the scheme then you havn't got it.

It's right just missed the 'ic' but they could think i know what i was saying but mispelt it like we all mispell things from time to time.

so you think i got it?

hmmmmmmmm hopefully I'll get 100 UMS or near enough with 40/45 :P

Well first of all you t.w.a.t this mark scheme isn't totally right. It's based on our answers and it's not from the AQA and they may accpet mispelt words as they realise you know what you were talking about so stop acting like a tosser

1a) Magnesium ions from the dissolved magnesium sulfate make the water hard (1). When sodium carbonate is added the magnesium ions from magnesium carbonate (1) which is a solid precipitate taking the magnesium ions out of the solution (1).
b) Result is anomalous/ doesn’t fit general pattern (1)
c) Water would boil off and there would no longer be 100g (1)
ii) 68 degrees C (1)
c) Two straight lines (1) which join at a peak (1) (as opposed to curve)
2 a) They are metals (1), react strongly with water (1)
b) Two elements in same box (1), some elements in same group had different properties (1), pattern falls apart after 18 elements (1) etc.
c) Left gaps (1) so undiscovered elements could be put into the table when they are discovered (1)
3 a) Transition metals unreactive compared to other metals (1) hard (1) shiny (1) (Max 2)
b) All have similar/same number of outer shell electrons (1) but 3rd shell only partly filled (1)
4 a) Hydrogen ion (1)
b) pH of weak acid higher (1) as less hydrogen ions in same concentration (which cause acidity in solution) (1)
c) i) Strong alkali, weak acid (1)
c) ii) 0.61 mol/dm3 (3)
ii) 12g (2)
5 a) i) Bubble gas through limewater (1) and limewater should go cloudy (1)
ii) Wrong (1), as white precipitate did not dissolve again when excess sodium hydroxide added (1)
iii) Right (1), as white precipitate formed after silver nitrate added (1)
b) i) Atomic Absorption Spectroscopy (1), Mass spectrometry (1) (Max 1)
ii) Measure smaller changes in the amount of lead (1)
6. Chlorine atoms smaller (1), so higher force of attraction between outer shell electrons and nucleus (1), so electrons gained more easily when they react (1)
7 a) -810 kJ/mol (3)
b) More energy released by bond making (1) than used for bond breaking (1)
c) Spark provides activation energy (1)

5a) iii) is no because in test 1 chloride ions where added in the form of aqueous hydrogen chloride (Hydrochloric acid)

H⁺ Cl^-

It frustrates me. We all just done a important exam and are worried about what we put and some tosser thinks he's got the right to say what he wants- **** off

yeah i suppose hopefully they give it as they have given it for past papers also mate, what did you get for the chlorine one whether student was incorrect or correct? i put he was correct, but then changed it to incorrect right at the last second, cos the silver nitrate reacted with the chloride ions in the Hydrochoric acid, and not in the eggshell?

There is no evidence that chloride ions weren't in the shell in the first place.

Look i was round your mums last night and im just saying what she said to me

You're seriously pathetic.

[Fas]

ladies you needa chill down, exams over nothin you can do. On a side note James_01 what school is that :P

Just because i go to the best school in the Country and you go to some ****ty school thats so bad even your mum wouldn't teach there doesn't mean you need to get angry.

Assuming I go to a rubbish school eh? Nice one. Well I'm not going to stoop down to your level.

Mate, you couldn't probably afford your own internet so your in school now pn your computer's so shut up or me and Zigggyy will deal with you

Home of stuck up bastard James_01.

Post proof though, i can say i clouds are green but theres proof theres not.

Inb4 you say you don't need to prove yourself to us, why mention it to us then?

[Aarongreatbanks]

James_01, pretty much your a tosser. If you were so sophisticated, you wouldn't be talking to us on the student room would you. You'd be consuming yorkshire tea and nice cake with your fellow stuck up wan.kers for friends so you're contadicting yourself here, tw.at

There is no evidence that chloride ions weren't in the shell in the first place.

There is also no evidence that there were either, so the student can't conclude that there are chloride ions in the egg

YET YOU HAVE STILL READ THIS MARK SCHEME, AND THINK IT'S CORRECT!

[ryazd]

should get like 40-42 for this exam, yay

[chloevictoria]

I put UV-vis for the instrumental analysis question... right or wrong?
