Today I did a Chemistry HSC Paper, Biology HSC Paper... and then 2 hours of bio revision. I'm happy, considering that I had other things to do/organise today.

Your total raw mark is 90/105. That would DEFINITELY be a band 6.

Re: 2007 Raw Marks for Maths (2U & 3U) The raw mark that you achieve in the exam (ie total of the marks awarded to you by HSC markers for one exam), is then changed/scaled/aligned by the Board of Studies, depending upon the exam's difficulty.. to a mark that is comparable to the rest of the...

Re: 回复: Re: When calculating eq. constant... There's no units for equilibrium constant... its just a figure that shows the extent to which the forward reaction in an equilibrium reaction is favoured, at a particular temperature.

Perhaps the mobility of delocalised electrons? This could be explained by the lower ionisation energy for elements as you go down the periodic table.. ie Group I metals become more 'metallic' and reactive as you go down the group. However... this isn't part of the HSC syllabus, and i've never...

Hopefully i'll be able to pull of a low 80's out of 105 Raw mark for english, to get into that band 6. For AOS paper, comprehension should be easy... creative will be a DISASTER.. and the essay should be ok as well. For Paper 2 advanced modules... I should be fine for module A, a bit mish-mash...

Re: 回复: Re: Question 18 from 2008 exam Just remember, all metal oxides are basic in solution, all transition metal oxides (except ZnO, which is amphoteric) are basic also. Al2O3 and BeO are also amphoteric. All non-metallic oxides (ie right hand side of periodic table) are acidic in...

English is pretty daunting to study.. I don't enjoy studying it either. I haven't done any practice essays these holidays so far.. have to get cracking. But I just HATE writing under pressure, that fast etc. there's no choice though...

Before the exam, two toasted sandwiches (multigrain bread) for breakfast, and then an apple just before the exam + little bit of water. It worked for my trials.

People that laugh at those who study heaps, ironically, are laughing at what they are incapable of. On december 18th, we'll be laughing at YOU.

I think they also use colorimetry as an extremely accurate quantitative analysis of turbidity.

Correct. The purpose of the oxy-acetylene burner is simply to gasify/vaporize the solution into gaseous ions. The cathode lamp then emits the light of certain wavelength.. which the metal cation absorbs... any 'unabsorbed' light is passed through to the monochromator, which as you said...

I revised the whole Chem course in 9 hours today (incl. the industrial chem option). Wow... alot went thru my head today. I really feel drained/lightheaded lol

yeah... surprisingly a big cut by the RBA. this is reall good stuff for our essays.... MUCH more to talk about (in terms of monetary policy stance). but this rate cut is no good for our exchange rates.. definitely going to depreciate.

Yeah, I was really happy with that question, I have to say it was quite easy. As soon as I saw it in reading time, I was relieved. I hope this year's Q3 Journey Essay question is fairly straightforward.

what minijumbuk is trying to explain is, is that: if there were 3mg of NaCl in 350ml Then how many mg of NaCl in 1L? 350mL=0.35L hence, the 3mg/350ml is the same as: 3mg / 1/0.35 L which equals 8.57mg/L =8.57ppm Remember, simply: ppm = mg/L

I think after 4th November you can register your number by sending a particular SMS message to a certain BOS number. That will register you for an automic sending of your results to your phone at 6am on December 17th.

That info is out of date (ie for 2007), and incorrect.

I just received a letter from the BOS in the mail. It has on the back the timetable for HSC Advice Line, as follows: Ancient History: 28 - 30 October Biology: 20 - 23 October Business Studies: 11 - 15 October Chemistry: 2 - 5 November Community and Family Studies: 1 - 3 November...

Since the supply curve shifts to the right... there is an increase in supply because the producer can produce more with the government's financial assistance, hence quantity increases. According to the law of demand and supply, as quantity/supply increases, demand decreases. Hence, there is a...
