ok, Well i done good for all the other questions except for the 5 marker comparison of two texts... How much are you generally ment to write for that section? and how many techniques are you ment to include for each comparison text? Generally to get 4/5 or 5/5 Also for the 1st question a) i...

Nope, destructive Test... Because you could probably lose some water molecules Evaporating.., Also if you heat it.... it would not maintain any evidence which it had prior... For example... Lets say there was a huge ice block, Which had bullet shots going through it... And you heated it into a...

A reducing Sugar has an O and a OH attached to the same numeric carbon that is the easiest way to distinguish them.

yea i realized.. the oxidized, and reduced terms.. but i'm talking about actually determining oxidation states of compounds,

Hey guys just wondering.... you's reckon Finding oxidation stated to molecules would be in the HSC, Because from all the past HSC papers i haven't seen a question based on it.... Therefore i'm probably not going to study it, But even the more reason for them too add it this year, correct?

Just too add, You wouldnt use Na2CO3 against ethanoic acid, as Na2CO3 with any carboxylic acid would produce CO2 gas.

^ I understand what your saying.... but i dont think it occurs in ALL multiprotic acids. If they are strong acids eg H2SO4 They have a 100% degree of ionisation, so it would only take 1 reaction to completely transfer all of its protons. So i guess the man problem for you in this question was...

Hmm yep, i would talk about all of the above, but im pretty sure u need to include calculations.. ppm= mg/kg Shouldn't be too hard.

We had the same question in our trials, maybe it was the same? My teacher after our results told us how to answer it. He said you would first talk about the DIFFERENCES IN FREQUENCY in red/blue light. You would use the formula C= frequency x Wavelength so, Frequency= C/ wavelength. The...

^^^ Thank you very much, I have a bunch of HSC past papers but couldn't find possible answers to any helps me alot.

+1 ^ Also when your in a car stopped at a Red light. if the person in front of you moves forward a little bit, leaving a gap you would then also move forward to cover up the gape, and in the process you leave a gap where your car originally was stopped, then the person behind you would move...

Thank you, to both the above posts. yep practicing alot :D, however making slow progress, some questions from the past HSC papers are so confusing :s

Well, what you have said in your chemistry exam.. about aphoteric and Feedstock. They are both relevant to the syllabus, the syllabus dot points could cover anything or everything stated in the point, For example the word 'biomass' is stated in one of the dot points, feedstock is related to...

I kind of don't get what you mean here, Why would you need the mass of oysters? it gives u the zinc content in 1 oyster, which is 200ppm that is all you need to do this question. We don't look at the oyster as a whole, only the amount of zinc present in an oyster. for example, Lets say the...

Sorry for the late reply :S okk well the general concept when dealing with ppm is that ppm = 1mg/1000g. That is something you should know while reading up on AAS. So by the given information.. The minimum daily intake = 12mg per day = 0.012g per day...

Nah mate, there's this guy who sits next to mee, names Robert Kiss, Does not have a clue what his doing. Lately hasn't even been let into the class since his always late. You can really see his level of commitment towards the HSC l

hmm, judging by your overall performance soo far with 50% to go, Your basically ranging average in a school ranked ~120 By what your wanting, i'd say you would have to Ace the HSC to get your desired ATAR. It is NOT impossible, if you manage to get band 5-6s your marks should scale to allow...

hey, thanks for your reply, appreciate it :D , makes my feel alot better I actually created another thread on this, since no1 replied to this 1 :S how do i delete this 1?

thanks guys makes me feel alot better. But can i ask what made you guys determine this estimates... As when i talked to my careers advisor and teachers and they said i would be lucky to get low band 5

ahh k, i was thinking maybe there is an award, awarded for just doing good in your raw HSC mark, it does sound more realistic then your total assessment mark. Ohh well. And yea, NO WAy i can get 1 know .. haha i was thinking maybe if it was your raw HSC mark i might have a 1/60000 chance but...
