Question 5 was related to nuclear chem and isotopes, but to answer the question you didn't really need to know about isotopes and stuffWas there even one question on nuclear chem/radioisotopes lol?

i talked mainly about Frasch. how this gives a high yield of elemental sulfur but causes many problems such as ground subsidience, soil erosion, thermal pollution (use of superheated water), dust and particulate matter. this has led to a shift in industries to obtain S02 from roasting of metal sulfide ores (in metall extraction processes) and natural gas.I talked about both processes. I was gonna talk about compromise in pressure since high pressure may lead to explosion of containers leading to escaping of dangerous SO3 gas to the environment but didn't have time... hopefully they give me 5-6
I also talked about how fossil fuels will most likely be used to generate the heat required so by lowering it, less CO2, SO2, etc. will be produced into the environment causing global warming and acid rain.i talked mainly about Frasch. how this gives a high yield of elemental sulfur but causes many problems such as ground subsidience, soil erosion, thermal pollution (use of superheated water), dust and particulate matter. this has led to a shift in industries to obtain S02 from roasting of metal sulfide ores (in metall extraction processes) and natural gas.
for contact process i just talked about high temperatures and this may cause thermal pollution if water is used as a coolant, and the need to monitor SO2 as it causes acid rain and stuff.
Certainly not the only one mate. In my school only the top 3 in the class remained. Others couldn't give a flying fuck about the exam.am i the only one who thought the exam was kinda hard? hoping for 65 raw
I know the feel. There was only two left in the exam room in ours. I ranked second, but everyone else is gonna do so shithouse that I can say goodbye to any chance of a band 6. Three quarters of the class left as soon as the first hour was upCertainly not the only one mate. In my school only the top 3 in the class remained. Others couldn't give a flying fuck about the exam.
Just look at data sheet, J Kg^-1 something else^-1What is the units for the specific heat capacity? Does it matter?
Specific heat capacity = 3.202 J/gKJust look at data sheet, J Kg^-1 something else^-1
I got 2.18 or something like that for that question.
What do u all think u got raw? I know for sure i got 18/20 for MC, and for sure lost 1-2 marks off in option, and 1-2 marks off core, though marking criteria obviously could kill off substantially more marks. As well as the fact I might not have picked up on mistakes I might have done lol.

haha mate its the same thing. 1 kelvin increase = 1 degrees celsius increase.. doesn't matteryeah its J Kg^-1 K^-1, but the temperature isn't in kelvin, so its not K^-1, thats why I'm asking.
A lot of people said the specific heat capacity is 2.18 or something, are you sure you're correct?Specific heat capacity = 3.202 J/gK
I got 1.22 :/A lot of people said the specific heat capacity is 2.18 or something, are you sure you're correct?
lol plsyeah. the 2.18 or whatever is right. I got that too and there is no way i'm wrong. It's basically just dividing.
no the HSC chem papers are not scanned, as they did not have the little right angles at each corner of each page. In business studies however it did, and i know for a fact that they only started scanning them last year. for now (2013) chemistry is not scanned, or it would have specific margins for which you would have to write it. dw, i wrote a fuckload too.Anyone know what the deal is with the scanning? Pretty sure I wrote well over the bottom line for the ozone question, but left a note at the top saying "wrote past the bottom line". :/ Really worried it won't get read.
