where can i find the safety requirements for different exps??? I realise in textbooks like Context, Conquering Chem dont have experiment parts O__O our stupid teacer never talks about the safety issues, he just says in the exam we pretend to say that 'We use small amount of blablabla and wear...

Thanks For example, for this question, do i just say 'add bromine water into cyclohexene' or do i need do state how much amount exactly, like 'Add drops of bromine water into a test tube containing 2ml cyclohexene'??? I just could't remember the details - like the fermentation, how many yeasts...

I mean the questions on the paper

Which one would u like to learn, Mando or Canto?

Okayy I PMed you

I don't mean the actual performance Im talking about the QUESTIONS on tha paper!!! That's like a report or something I'm really weak at the experiment types of questions I have no clue to start??! What should you consider when you have got these questions? Do u write like hypothesis...

Ooops sorry it's Jess lol Why do you want to learn Chinese? Where are you originated?

Hiiii paraplegicmeiliz Yooo what's up

Well, i reckon this has nothing to do with my accent? I was approving the comment that I personally think OP wrote all of this thread in a Chinese accent lol It just reminds me of my Chinese friends writing ^^

No worries haha The thread isn't that old mate? But the comment I was quoting is just funny

Bump

I don't think theres any need to explain WHY O is more electronegative than H. We just need to mention it IS δˉ while H is δ+ and hence it forms hydrogen bonds with other organic polar substances. That's the reason why it will dissolve polar sub. And it has non polar alkyl group which will form...

Thank you! Of course I know these fundamental stuff, can't learn hsc Chem without the basics right? Just wondering if I will be tested on some details such as the electron arrangement of water, the bent structure, and explain electronegativity trend across period and stuff like that???

Thanks for noticing I don't do physics haha good memory! Well I know for maths it links with the prelim stuff. Mainly ask for Chem, will they ask questions from prelim? Is there any need to revise prelim chem stuff?

Oh wow great thread! Unfortunately our school uses math in focus

Or does it depend on a particular subject?? Well I know for maths it links with the prelim stuff. Mainly ask for Chem, will they ask questions from prelim? Is there any need to revise prelim chem stuff? Of course I know the fundamental stuff of chem, can't learn hsc Chem without the basics...

Our school uses surfing 4 chemistry and I actually find them actually really help me understand the contexts. I use surfing for my revision of chemistry. =) But you can borrow it from the library first and see how it goes. They are actually unreasonable expensive!

Hey many thanks! Btw do they ask prelim stuff in HSC? I thought it was all about yr 12?

Do we need to learn about isomers? I've noticed that there were types of questions about isomers appeared in past paper, but I couldn't find it in syllabus anyway and it has become a concern that I havent come across about these sort of questions So is it in the syllabus O_O

Ah I did English yesterday =] Didnt quite figure it out tho, it was meant for Standard and Advanced :/
