Is anyone else TERRIFIED for the chem exam this year? 😭 (1 Viewer)

[Wildhalberd]

wish it was held on 4th of november like last year

Yeah - after coming out of maths, I feel like we would need the extra time to prepare for chem...

 

[C_master]

ima just do one quickly from reading the syllabus if anyone still needs it
- limitations/advantages of Arrhenius and Bronsted-Lowry
- Acid/Base in industries, by Indigenous peoples, with technology, in neutralisation
- Buffers in natural systems
- All the organic reactions
- Soaps and Detergents
- Environmental, economic, sociocultural implications of using/obtaining hydrocarbons
- Polymer structure/properties/uses
- Biofuels
- Precipitation reactions and flame tests
- Environmental, social, economic issues for chemical synthesis

Is that all?
I feel like theres more idk

What do we need to know for complexation bruh - I just know cobalt hexahydrate and iron thiocynate

silver ammonia complex is sometimes in ion testing, but other than that you should be good

Is that all?

I think cheesy covered it perfectly but here are a few more to add


Collision theory explanations for changes to equilibrium

Intermolecular forces involved in different organic substance classes (e.g alkanes, ketone, alcohol, carboxylic acid) AND link to properties (BP, solubility, etc)
- Nomenclature may be something worth revisiting with regards to substituents naming (e.g have to be in alphabetical order, first point of difference) and for amides/amines

Conductivity graphs (espec less intuitive ones like WA/SB or WB/SA)

Factors to consider in chemical synthesis (yield, rate of rxn, etc)

Whats the odds of polymers coming up given it hasn't for the past few exams

very high and im not happy about that

i swear if i see a map of potential ammonia factory sites imma crash out

 

[yourlocaliga]

guys when do you even use complexation reactions i acc dont understand

wait holy shit u havent had an exam since english

 

[C2H6O]

wait holy shit u havent had an exam since english

yeah been slacking so hard its really bad

some ppl already finished hsc i havent even done a second exam yet

 

[C2H6O]

guys when do you even use complexation reactions i acc dont understand

thiocyanate is your classic calibration curve absorbance example
cobalt hydrate is classic equilibrium example
silver ammonia and copper ammonia complex used in ion testing (oh yeah @Wildhalberd forgot bout copper ammonia)

Why is the BOS paper so hard ;-;

Why is the BOS paper so hard ;-;

It’s supposed to be dw i got 50% on the 2023 i think it was
