Haha... (ok u werido) lol... what mark do u rekon will be band 6 cutoff...?

Yep, was a pretty easy exam...the virgil autho commo was exactly what i'd studied so yeah it was sweet...umm the virgil unseen had a tricky sentence in there but i think i got it...:D one more tomorrow :(

That's correct I do have latin coming up...looking foward 2 that scaling :D

I didnt bother with the m/c...it was a bit of a joke and im a busy man

Nup man... but I have a fair understanding of the course and took the liberty of doing the paper about 1/2 an hour ago..

My opinion is tat the manhattan project was very predictable... I agree that chem helped with cloud chamber but they really made the radioisotope calcuations a joke! :D

I got 89 in cont and 46 in extension...my teacher is head marker of extension :D

Man the 2NO2 is just the mole ratio... there was still .132 mole added initially...

yep perfectly correct... surprised more people didn't get this... 1) it's easy lol and 2) it's been in a past HSC (like 02 or smtin)

Yeah looks ok to me...but remember u had 2 define Le Chatiler's principal before applying it in ur explanation...:D

reliability: are we able to reproduce the results; the consistancy of the results accuracy: percision of equipment and measurments validility: is the method appropriate for testing the particular characteristical feature thats's being tested. Hence repeating exp will increase reliability as...

Are u guyz serious about 85-88 for band 6... if the top in the state for chem only gets like 96...band 6 will be like 77/100. 88 will give u like 94/95 :D:D:D

I know 1 is B...but the defonition of an atom is something neutral isnt it...so D is also correct, if they had said "ion" then yes wrong, but they said atom...hence number of protons = number of electrons. ie excess of electrons = unbalanced ration neutrons:protons, ie radioactive. Someone pro...

I think they've made a boo boo in that question...because I can't see why its not D...although I know B is correct

Actually on review, I think we are wrong...lol brain freeze. Because elements with atomic mass >83 are radioactive...so hence too many neutrons and protons. But can someone tell me this: isn't the defonition of an atom something neutral right - where number of electrons = number of protons...so...

Lol they were easy...but I dunno about question one...radioactivity isnt about too many neutrons and protons is about raito of neutrons: protons. So D is the answer because too many electrons = too many protons for the number of neutrons...I think anyway? My answers were: D, C, B, D, B, A, C, A...

U wrote an equation: 2HCl + CaCO3 ... Moles of HCl worked out using concentration times volume (litres) Then the titration worked out excess of HCl, so u found number of moles HCL excess using voulme and conco of NaOH then mole ratios. Then u subtracted the excess from the original mole of...

No top of the state raw mark is about 96/95...they are so bitchy in marking

Basically out performance as a 4unit candidature in 3 unit shows how good we are to the bos...so our 4 unit exam, if the marks were low, looks harder or smthin...ie our 4 unit marks are scaled up...

All u had to do was half the interval twice then u found the new range was between 0.7-0.75 - hence the root had to be equal to 0.7 to 1dp...what's the confusion? And wasnt 2003 2 years ago...somebody fill me in?
