Expecting 100 raw mark like many others here but my responses were very solid :P Expecting 1st in the state and my dream ATAR, 99.90 :D

I looked at solutions and should get high 60s. Last year 82 scaled to 96 so I was aiming for 82 but made many mistakes in questions 13-15. Phys is my second best subject (after chem) so hopefully I do well tomorrow. If I don't get 99.90, I need to change all my plans...

Fucked up 4U maths... hopping for at least a B6. 99.90 is almost impossible now. Unless I get like 95 raw mark in physics tomorrow. Fucking hate my stupid maths teacher, made me hate maths so much :(

18/20... made silliest mistakes :(

I also talked about how fossil fuels will most likely be used to generate the heat required so by lowering it, less CO2, SO2, etc. will be produced into the environment causing global warming and acid rain. I think this is the worst industrial chem 7 marker ever. In past years, it wasn't so...

First in the state is usually 98. Don't think it ever goes to 99.

I didn't use textbooks at all. I bought notes and used them as a guide to make my own. if you make your own notes, you pretty much never forget the information.

Most: industrial chemistry Least: First half of acidic

Would 94-95 raw scale to 98?

I talked about both processes. I was gonna talk about compromise in pressure since high pressure may lead to explosion of containers leading to escaping of dangerous SO3 gas to the environment but didn't have time... hopefully they give me 5-6

HInd_{(aq)} + H_{2}O_{(l)} \rightleftharpoons Ind^{-}_{(aq)} + H^{3}O^{+}_{(aq)} Then you talk about Le Chatelier's principle and how colour of solution changes as concentration of hydronium and hydroxide change etc. It can be used as an indicator since colour change is distinct.

No.

In the table I'm pretty sure AgNO3 is the limiting reagent. After that you use ratios in the equation to find the moles for everything else. BaSO4

Pretty sure this is right.

Will 94-95 raw mark scale to 98?
