Has anyone else been struggling with getting back into a study routine since trials? I've been really slack with any kind of prep in general and that realisation will hit hard soon.
literally everyone ive spoken to has this problem. I guess we are supposed to slog it out for the last month.

im not forgetting my exam period is over another month :newburn:

HSC ECO students where we at 🔥

I’ve decided to run a free 1-hour seminar that will break down an essay question I believe may likely be assessed in the exam. This question will be on International Organisations, and I have a solid band 6 calibre framework that I’m really keen on sharing

Having achieved a sr mark in eco and ranked first in a top selective HS, i do think i've got some insights that I'd love to share and just general tips as well to help you achieve your best.

THERE's always still hope - please fill out this expression of interest form to help me gauge numbers: https://forms.gle/ZkKBsuragciNYzRR8

It's in the early entry offer - mine was like 11 points higher than my estimated using my trial results lol
Bro they gave me a 99.95 and atar calculator from uac gives me a 85 for my year 11 results...
Literally would not trust anu

Hey, I'm currently in year 10 and I've decided to study Chem earlier this year! Could anyone help me with these two problems? Its just these two that I am really stumped on 😭 I'm asking on this thread because you guys are in senior school 👍

1st Question ) I get the gist of this question, but I'm stuck on how to find the total hydroxide concentration from the two samples. Could you explain how you got it please. ( Answer is E ).

( 2nd Question ) This one I really don't understand and my friends are sooo unhelpful😭😭 Could someone give me a full on way on how to solve this one. The answer is ( A ).

Chemistry is definitely the easier one out of the three sciences. Physics is getting really undo-able might have to go tutoring for it next year 😭
the first one u take the stoich in the molecule itself. Ba2+:OH-= 1:2 and accordingly add moles of OH, divide by volume

second one gave u more info than needed to make it tricky. just find the moles of c6h12O6, then divide by the volume. THe concentration is maintained in a sample because we are considering molarity which is a unit/volume. hence, even if u had a 10ml volume extracted from the 200mls, the 10mls still has the same concentration.

So... Ba(OH)2 can disassociate in water. we then can consider it through its molecular ratio. For each Ba2+ ion, there is 2 OH- ions. Since you have x amount of moles of Ba(OH)2, you have 2x moles of OH- ions. You then can do the same thing with the NaOH and add the OH- moles up. From there you divide by the volume of the BaOh and NaOH

Yeah... Thats what I was thinking as well. Its just I don't know what to do from there. I know the basic fundamentals, but I can't make any progress with it. Its really fustrating. 😭 . I hate Molarity and Molaity so much ( Anything to do with concentration, to be honest ).
it takes heaps of practice mate. It's good you're doing things now. I wish I did that when I was younger lmfao. Lowkey just grind this shit out instead of your yr 10 stuff if ur confortable w the content. Genuinely, the chemistry course for yr 10 is a joke. Basically the same shit/less than the yr 9 syllabus. You can use that time better.
