    Chemistry Marathon (HSC)

    Yea I was just wondering if its bent shape is enough to conclude that it's polar, because the net dipole is 0.

    Thanks for the reply, is this the extent of the detail we have to know for a band 6 response?

    Ready for Information Technology?

    Yes I did...I found IPT bullshit tbh as I spent a very long time studying the syllabus, and learning everything from it. The test (apart from MC) basically addressed <50% of the syllabus so it was mainly about reading the scenario and bs'ing..I was pretty disappointed- some of the questions were...

    Ready for Information Technology?

    Yea but none of them are correct haha...major fuck up by BoS. Just because there is high CPU usage doesn't necessarily mean there is poor performance- you could be rendering multimedia project that is using 100% CPU, that doesn't correlate to poor performance.

    Hey guys I just had a quick question (sorry deswa lol) What makes ozone more reactive that oxygen? Is it because the co-ordinate covalent bond is weak? If so, what makes it weaker than an ordinary covalent bond? And what makes ozone slightly polar? It's a bent molecule but its net dipole is 0.

    I put D as well. But technically none of the options are correct.

    That was such a poor test, IT such a dodgy subject. Q14 is wrong.

    Band 6 cut off?

    Does anyone know the raw mark cut off to attain a B6 in this subject? I've just started my revision and the syllabus is massive..I should be alright for the exam though, just curious

    Question 14 Solutions

    Q14 b iii) when you say 250sin^2x >= 150, the next line is sin^2x>=1/2. 150/250 is not 1/2...at least i don't think so O.o
