fairly certain the last question is 0.39 - if you got 0.53 I think you forgot to subtract the [BrCH2COOH](octan-1-ol) from your value of [BrCH2COOH](aq) in the Ka expression

don't you use Ka first to then get Keq bc that's how I got 0.531

lol I just want to know if I can some marks

Does it matter anymore

Thoughts on scaling/difficulty compared to last year?

 

[ManifestationIsKey]

I think it was more difficult than last year and I would say around 2022 moderation. So carrots calculator would probably fit fine for this one. 85 for B6 and 69 for B5.

friend sr'd last year and said it was easier than '23 but longer ;p

 

[Pielavender1234]

ikr why was there close to 40 questions

Then B6 should be 88 or 89 lol and b5 should be around 73 - 74

sr1 said it was harder tho

sr1 said it was harder tho

Imma believe him, whatever benefits me

 

[cute lil monkey]

what b5 raw

 

[ManifestationIsKey]

According to SR 1 (who said the test was harder than 2023 so I assumed 2022 difficulty):

85 for B6 and 69 for B5.

According to another SR (who said test was easier):

B6 should be 88 or 89 lol and b5 should be around 73 - 74

So I guess we'll just find out on 18th december

i think i got 20/20 based on the post before
i guessed 17 and 20 lfgggg (educated)

Nah it’ll most likely be 85 for b6. 88 or 89 is too high

How many marks lost if I put 0.53 for the last question instead of 0.39? Last question is out of 4

They give you 1 mark for writing the balanced chemical equation basically and 2 marks if you did something correct in the working out, so basically if you just make a calculation mistake i would say you might get 2 or 3, but most likely 3/4.

1 or 2

I think 1 is kinda a stretch, they give you 2 if you did something right bro

what was the balanced chemical eqn u were supposed to write

 

[ManifestationIsKey]

what was the balanced chemical eqn u were supposed to write

Im pretty sure it was BrCH2COOH (reversible arrow) --> BrCH2COO^- + H^+ and all are aqueous and then just write the Ka equation

Boy your answer might be right lol. GPT saying its 0.53.
