HL chemistry aftermath

Yeah so i fecdked that up but i dont even need to pass it so its ok XD ill be ecstatic with a d3!
hope you all got on great though..god bless that radiation question!

Overall I was pretty happy with the paper. Got all 11 questions done so I'm pretty hopeful that the result will be alright.

Some of the questions on the experiments were a bit dodgy though. I didn't think the name of edta was on the course. And wtf is the IUPAC name for glycerol? I couldn't find it in the book.

Was aiming for C1 or B3 and I think I got it, so it wasn't too bad.

wayhey

It went okay.. I just hope I got the C3 minimum... where the hell was bleach though?

IUPAC Name of Glycerol: propan-1,2,3-triol

edta was definitely on the course - Our teacher made us highlight it and put big huge stars around it so we'd learn it haha. And kept making us say it....

The IUPAC name for glycerol is propan1-2-3triol. It's not in the book (if you have chemistry live).... Our teacher made us write it in beside glycerol though. I had to visualise where I'd written it on the page to remember it hahaha! And then I wasn't sure if I was right! :P

Very pleased, by my low standards that was fine and I think I got a high C. The others in my class (all aiming for an A) thought it was a hard one.

Q4 and the equilibrium question were easy, you had passed it with just the definitions.

ummtea

I think I passed it. Seriously!

oh well...*burns books* glad everyone got on good looked like an easy paper if i read anything because i recognised all of it! XD

haha np, those things are only worth a small amount of marks anyway. I don't think they'll make a massive difference...! (I think I read before you were looking for an A?)

As for me, I went into the exam thinking I'd fail and came out with a possible B! I think I'm the only person who liked Q5 though....! :rolleyes:

Glycerol is propan1-2-3triol? Right... I hazarded a guess with "1,2,3-tri-propanol"...

Yeah same wtf, I can't find the glycerol one either! I left it blanck though, so if they decide to give out marks to anyone who attempted it, I missed the boat I feel awful after that paper, and I thought I'd be getting a A1. Thank christ its all over now though. Finished, and never have to do a leaving cert again! Touch wood

Just one to go now!! Thought it was reasonable, there were some nasty bits, like Q9(f) which our teacher said wasn't on the course, and Q11(c), which gave no choice for the manufacturing stuff, where I'd done magnesium and not oxygen. Q5 was awful too. Still reckon I scraped the A1.

I just hope I passed It was okay but nothing amazing by any means

Captain-America

That test was fúcking horrible.

lc2010

Though it was a tough one really, hardest in years.. A lot of little tricks in the questions and predictions weren't that spot on...WHERE was py precious volatile liquid and bleach??! Hope I scraped the A1...debatable though!!!

whelpy

What the hell was the story with the Industrial chem q in 11.c)?!?!?!?!

It was only about air manfacture, but our class only did ammonia
I thought we had a choice between the 3 different case studies :mad::mad::mad:

same!

i've seen variations of other iupac names so i'm going to go ahead and say we're right too!

No it's like ammonia or magnesium, but Oxygen manufacture is on it as well. (I knew that but STILL couldn't answer :P)

I wondered about that as well actually, I thought they had to give the choice?

It is mentioned. Only once though! Page 353.
I didn't get it, btw...

I really hope they mark this year easy, so many of my explanations just waffled on.:(

Apparently, as my aunt has just told me, Oxygen is part of Atmospheric Chemistry, and therefore not optional. The batch process thing was thrown in to confuse people.

My aunt is a chemistry teacher BTW.

I <i>killed</i> myself for that paper,
& yet I still think I've failed. Please God I'll get a D3, I only need it to pass, I'm not putting it towards points

Making It Bad

I hated it. I really really hated it.

same here.

sheep-go-baa

Wasn't a bad paper really just small parts like Q9(f)
hadn't a clue:rolleyes: lol

leavingcert

Lovely paper

Tricky bits but over all very happy

Hoping for an A or high B

aine92

I thought it was a nice paper, ****ty organic questions, first time I have ever done a paper without doing organic, but overall I thought it was nice!

TowlieMcD

Q5 was nothing short of *******! i was hoping to get full marks in it and then DALTON! who the **** is dalton? there's prob only 5 lines on the bastard god forgive me. pretty hard paper...might get B3 at best

hmmmm52

ha ya i'd say there actually is just 5 lines.....i thought q.5 was grand though organic questions were horrible!
any1 take down their answer for Kc in equilibrium q??

2.25 I think.
