No worries champ, im sure u deserved what u got, an got into the courses u wanted. Take care buddy thanks for the advice.

Yeah tere was like nothing seperating me and first at school, i thonk he got me by 1 mark in the trial and snagged first :/. But hes already done the chem course at uni so he shreds pretty hard. Also congrats buddy, nice atar :) i only came up 92 :s but i guess with my unsw schollarship and hsc+...

Yeah, well my teacher has been marking hsc for the past 10 years and teaching chem for 28 years, and i always had her marking my past papers. Also is it possible that me bpmbing it affected the assessment marks? And thanks for your help too.

Oooooh okay, uhmm second with 85. This i making sense now, but still not sure how i bombed the exam so hard

Oh, okay, but i thought, if she got the second mark and i got the third rank mark it would turn out to be the same exam mark? Keeeping in mind there is a huge gap between the top 3 and the rest of the class. Also yeah, massive shock, i thought i wouldda got 90+ raw :(

Does that sound fishy to you though? Is it worth it? Keeping in mind im so poor atm haha.

So i was very confident in my chemistry exam, i did every past paper from 2001-2010, and consistently scoring 85+ raw. I was ranked second at my school, and my exam mark for chem only came back 81???? Which gave me a hsc mark of 83. Now the girl ranked third in my school got an exam mark of...

My mistake, i didnt read the plural in distances. Ahwell 19 :)

What? As u said the Repulsive force is dependant on the current? Sooo te current is the independant? If im mistaken, the distance between them will change unless the top rod is fixed.

Hopefully 95ish :) was very easy, short exam. Plenty of time to check answers/3 good pages on the astro 7 marker. Should only lose marks through mc, sillies and markin criteria :D good note to finish the hsc on. Chyeeaa

Its a repulsive force between the two rods because tey have a cureent in different directions. Hence the distance of the ro depends on the current that glows through them?

1. C 2. B 3. B 4. C 5. B 6. C 7. C 8. A 9. B 10. B ( isnt d incorrect? Because it changes dependant on the current? Ie the current is the thing u change? Correct me if im wrong) 11. D 12. D 13. A 14. A 15. C 16. B 17. B 18. B 19. D 20. D

U all thought i was crazy :) i knew 15 was A.

It ionises fully because of the fact that its a weak acid. Consider the equilibrium reaction in which the hydrogen ipns are produced. As the hydrogen ions are removed due to the hydroxide of the base. More of the acid ionises, hence it has to do with the amount of protons not degree of ionisation.

Yupp, because theyre both monoprotoc, the degree of ionisation woll affect the end point, not the volume needed. Eg citric acid requires alot of strong base to neutralise despite the fact it is relatively weak.

Im feeling pretty confident about them, some were tricky, i think i got the bromine water one wrong, out of panick. And i didnt get to check my calculations due to time but my answers seemed not too bad. 15 i think was quite tricky. But im happy with the conclusion i came to :) hopefully 17-18

Good exam, ~90. Forensics was easy. So happy to Do well after the 2 hours of buttfuckage that was MX1.

Yuuuuusss on a brighter note, looking at posted solutions i might not have done that bad, and i have a good rank. Thanks guys.

My parabola wasnt comming out properly and i was trying to figure out what id done rong. Before i knew it had 50 minutes to do the rest of the paper D: completely lost track of time and had to rush almost everything. Fudged alot of answers, didnt have time to check anything. Didnt attempt a few...
