Hey,

What did everyone think?

Did anyone get prop-1-ene for the compund in the last question?

Also, what did everyone do with that diagram question and what did everyone write for the Vitamin C question.

Did anyone get 55.55kg for one question (can't remember which one).

[Terrence]

For one part of the last question I'm sure I got an -yne.

55.55kg sounds familar

The Vitamin C question = panic

And, what diagram are you referring to? [I'm sure there were more than one]



I've made so many stupid mistakes and I know it.

[Ally]

The diagram where you had to arrange stuff, it included a magnesium ribbon. I think i got that wrong as I didn't understand what it was asking you.

As for the preperation of esters diagram I forgot to put the paper towel condensor at the top of the test-tube. DAMN! lol (I went through all the PPA's drawing the diagrams yesterday)

Did you get that Vitamin C was in excess?

[Phoenix]

vit c was in excess by like 0.12g, so i said the iodine solution turned colourless.

I also got 55.55kg, though i ran outta time for 6 marks worth of questions! i just had 2 rush through them all at the end cas i spent way too long on the multi-choice

[wallet inspector]

Almost EVERY multiple choice was a repeat of a previous one, didnt even change the possible answers

Overall felt it was the easiest exam so far, a couple of wee tricky bits, but overall pretty decent

Yeah, I didnt really know what i was supposed to do with the magnesium ribbon question.

Also got 55.55

Exam was good, plenty of past multi choice questions as well. I don't know about the diagrams, I bluffed my way through them. It was PROPYNE you needed for the second last quesntion, as it was a triple bond. Has anyone else noticed that all the problem solving for most highers is straight out the associated advanced higher KU.

A here we come:)

[Ally]

Oh yeh I meant to say propyne, I got that aswell. Just that I wrote prop-1-yne instead.

[werlop]

Prop-1-yne is good as well, but the -1- is not needed becuase of the number of carbons - it is a symetrical molecule.

[Ally]

What did you get for how you measure the molar volume of Hydrogen?




Oh and btw, does anyone know how CO2 can dissolve in water.

[xpurple_starsx]

What was 55.55 for? I've so messed up...

[Ally]

It was for the mass of Zinc, the question where you had to use Q=I*t


In the multiple Choice did anyone get D (3+4) for the mass of the ions.

[Ally]

What did everyone get for the raw material for the M.C paper (I went in the exam, knowing hardly anything about Industrial Chemistry, not the best thing to do).

Also what did everyone write for the flow diagram?

Did anyone get the reaction to be a displacement 1?

Also, did anyone draw the sulphuric acid going into the neutrailser bit?

[mel]

Hey I think i put sodium chloride for the raw material question.
I put displacement for one of the questions too but I dont remember puttin 55.5 for any of them.
I got 3 + 4 for the mass of ions.

Did anyone else find the last question strange??

[Rubberducky]

hey im totally undecided on how i feel the exam went, in one way i dont think that it was too bad but i still have a bit of doubt. I was totally pushed for time for checkin things over at the end. Overall i thot that it was hard, quite alot of guess work!
