Listing the BIG questions (1 Viewer)

[Managore]

Could everyone list the possibilities for the 5+ mark questions? the big ones that I know I won't remember much on and thus fail the course ...

~Medical and Industrial Uses of Radioactives
~History to haber process to make ammonia
~History of definitions of Acids and Bases
~What else? I can't think anymore..

Thanks in advance, by the way

 

[lucyinthehole]

any experiments we've done
neutralisation
something about water quality/management?
AAS
named scientist + methods they employ
biopolymer
possiblity of use of ethanol as fuel

there's heaps more, those just off the top of my head

 

[danno]

probably something to do with CFCs or ozone as well.

 

[Tommy_Lamp]

The first one will only be about 4 marks, the second would only be 2 or so marks, the third isnt a question, they can only ask you specific definitions.

Major ones that could be 7 marks:
Water treatment
Biopolymer
Importance of monitoring Haber Process
Affects of oxides of Nitrogen and Sulfur on the society and the environment

lucyinthehole: I've seen so many people make this mistake, YOU DON'T HAVE TO KNOW A NAMED CHEMIST, YOU NEED TO KNOW A NAMED BRANCH OF CHEMISTRY.

 

[LSP]

refluxing, esterification
Pollution
ozone related like CFCs
titration
decarbonating softdrinks
battery
water stuff
biomass, biopolymer

prob there is more possibilities

Every single point on the syllabus is a 7 mark question possibility. Sadly, that's the way sciences go - and I know will be the reason behind my downfall tomorrow.

 

[Tommy_Lamp]

hfis: not at all

"outline the role of a chemist employed in a named branch of industry or enterprise"
hmmm, i guess that is to be interpreted kinda like "the responder" in english is. just a general, hypothetical chemist, as opposed to a particular one. but you can see how it's possible to interpret the other way, don't you?

 

[Managore]

~History of definitions of Acids and Bases

I meant by that lavoisier's definition, davy's, arrhenius' and bro/nsted-lowry's definitions

 

[ben7]

Wats an example of a 7 mark Q for water treatment?

i think u overlooked the identify "a is b" type stuff on the syllabus.
but apart from that, most are 4 markers, and only some 7 markers...

 

[Paroissien]

You would be asked to assess or detail the steps in purification of mass water supply.
I doubt it would be 7, but there is a 5 mark question on it in 2002

oh yeh i done that one.. ^ i just forget.

 

[Doogsy]

they can also ask a question which combines several dot points into one large question. they have done that in the past

Yeah I can see what you mean, but trust me, all you need is a named branch.

 

[Tommy_Lamp]

"Outline the role of a chemist employed in a named industry or enterprise, identifying the branch of chemistry undertaken by the chemist and explaining a chemical principle that the chemist uses "

 

[DAAVE]

Yeah just do analytical chemistry. A chemical principle used is absorption for gas-solid chromatography...

This is used in the industry for monitoring the quality of ethylene produced like at the Qenos plant.

according to Conqering chem anyways.
