Maybe two marks lost because it was just a simple c = n/V question, there was nothing much to do except for Z u had to use a mol ratio. Btw the order was Y, X, Z right or am i tripping

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

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

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

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.

According to SR 1 (who said the test was harder than 2023 so I assumed 2022 difficulty): According to another SR (who said test was easier): So I guess we'll just find out on 18th december :)

Imma believe him, whatever benefits me

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

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.

There were some questions that weren't that easy, but I think they were generous this time with the 7 markers and overall the exam was easier than expected.

Good Luck Everyone. Take it easy and think about a question with a cool mind. If your really stuck move onto the next one and the previous one will eventually come to you. We all got this guys :)

Yes it is accepted. It is still a universal way of representing the structure, but as @shoulfer said, it would be preferred to stick to structural, but I doubt they would penalise for having a skeletal structure

Do we, I thought they usually give the condensation polymers and then tell you to show the monomer, but you have to remember the addition polymers for sure.

I would just know the basics of how they work, they could possibly asked very deeply as well, so best to know it

Please no! Just no :( Genuinely hate this waffle They could ask for comparison between addition and condensation and then an example each and maybe its uses, probably like 7 marks

Atp im just relying on the Ksp table. Whatever is on it is insoluble lol. Could be but tbh idk how they can make the question very long and for a lot of marks. I reckon the long response questions this year maybe on soaps or instead of long response, they could just give us a long calc.

All we can do now is try our best. Think about it, if its a easier test you should go through it slowly (still finish in 3 hours) and make sure you don't make many silly mistakes while being overhyped that the exam is easy. If the test is hard, then its gonna be hard for others as well, so the...

No beforehand im pretty sure

Yh, im pretty sure MOOC is for usyd only and other uni's offer bridging courses, but not exactly sure, so best to search it up :) Also I am not sure whether bridging courses start from the basics, but MOOC does.
