VCE Chemistry Exam Discussion and Solutions (in progress)

[lovebiology]

A copy of the exam?

[TRA0023]

I reckon it was the volume of NaOH. That's what I put anyways, pretty sure I'm wrong.

I had the volume of NaOH as well. :/ since it was the only thing I noticed that changed

Hi what study score would an exam score of 117/120 with rank 1?

50.

In 2013 I know of a 114.5/120 that got a 50.

[tigerlily28]

PEM cell was just a 02+2h2 ---> 2h20 reaction.

Thank goodness! That PEM question threw me off, but not as much as the last two questions.........Also what did everyone else get for the last multiple choice question?

[Rusten]

new study design how was it?

which past exam was it's difficulty comparable to?

Not really comparable directly to any I'd done, lots of theoretical stuff not much calculations. Overall not that hard to except a bit about travelling to mars and evaluating its 'feasibility', and some of m/c but that's more cos I didn't study until the weekend heh

[JOHNSMITH II]

Yeah, most of the exams ive done thus far have been quite different from previous years (at least it felt so to me), chemistry was no exception

How about Rank 1 with about 105-110/120, what kind of range am I looking at there, anyone know?

I haven't seen the exam but around 42-45 from what I'm hearing about the exam

[lovebiology]

Does anyone has Solutions of the exam?

[Deonyi]

Is it just me was there an error in the question regarding the fluorine cell? It said something like 'water when in aqueous solution, becomes K+ and F-'.

[Ahmad_A_1999]

I put that as well, that was the only thing I could think of

[The Bus]

I found the overall difficulty much harder than the sample.

There was so much more worded questions than usual.

Also, for the independent variable, I can’t remember what I wrote but thinking about it, the volume of NaOH could we possible. But then again, we aren’t technically changing this variable.

You could probably claim that the brand of the chemical used is the controlled variable, so it can’t the independent variable.

That mars question was fucking lame. VCAA should’ve had Q9 or Q10, not both. Way too time consuming.

Yeah they usually only put one of those sort of questions, I was stressing out towards the end trying to read all that damn info about this moron's stupid titration

[Deonyi]

The independent variable probably was the concentration of the NaOH since he controlled it by making up the solution to a specific amount. I put down 'the titrant used' so I'm not sure about that mark.

[waterangel82]

I had the volume of of the tartartic acid as the independent variable - not to sure because volume of aliquot usually affects the amount of NaOH delivered?

That’s a controlled variable lol.

I think water angel is correct. The independent variable is probably the tartaric acid used. Completely overlooked that since they were all just 10mL...
