Crazy stupid calculation never seen before

Oh on what topic?

 

[MrGresh]

Oh on what topic?

There was an equilibrium calc which was whacky, a precipitation titration and an enthalpy calc but I can't remember the rest

 

[4u Boy]

Oh on what topic?

Titrarion, precipitation titration as well, enthalpy of neutralisation (last qtn) weird Ksp pH

Oh on what topic?

One of them was on finding an equilibirum constant given all these stupid equations connecting the concentrations of each species

 

[jazz519]

It was so different to what I've seen before. A lot of the questions seemed very hard at first but turned out to be easier with some problem solving and thought.

But definitely harder than 2019 by a SIGNIFICANT margin

Yeah this is to be expected the 2019 paper was the first of the new syllabus so they probably set a medium difficulty as a baseline, but the 2020 HSC paper is probably going to be reflective of what will now be the new normal for the chemistry papers

Yeah, true. Honestly it was a good difficulty. You wouldn't be able to do very well at all without knowing your stuff well.

I usually like calculations but these were so different

 

[Luke322]

What max. temp did you get for the last question?

I got like 77

The calculations were really conceptual like you had to think laterally. So much harder than last year

 

[NN03]

I got like 77

Damn. I screwed it up.

 

[Mazar97]

This exam was so much harder than last yrs.

What was the answer to the pH question, where part one was like, show that the concentration of calcium ions is 0.1mol or something?

11. Something don't remember

 

[4u Boy]

11. Something don't remember

.385 maybe?

 

[Xanthi]

11. Something don't remember

Yeah I got that

 

[4u Boy]

Q20 C??

 

[Husky]

Q20 C??

Yh

 

[4u Boy]

Yh

Noice

 

[Luke322]

.385 maybe?

Yeah thats what I got as well

 

[Luke322]

Damn. I screwed it up.

I don't know if I was right tho
