General Thoughts: Chemistry (3 Viewers)

chemistry is easily my weakest subject but i was pretty happy *could* possibly (fingers crossed) scrape band 6

isnt it -57kJ/mol because the net ionic equation for all neutraisation reactions is essentially H+ + OH- ->H2O

Industrial 7 marks...so who else wrote like 2 pages?

Me.

I believe you are correct

 

[utanobeiiby]

i got the exact same but surely that is too high

its around 0.31M you might've not calculated the [NaOH] correctly ..

Your situation is exactly the same with mine

lols i got about 3

yeah like i'm very comfortable with physics on friday, so for me hsc is technically over with chem lol

 

[utanobeiiby]

an experiment is not a model.. its a real thing... im thinking when they say models they meant like balls and sticks and computer simulations stuff.. well either way i skipped that question cause i can't write some BS about balls and sticks><

 

[utanobeiiby]

I mean his principles and other shit? correct ?

yes but you should realise the last step is not an equilibrium reaction and le chatelier's wont apply... and yield is always 100%

Shit

concentration of citric acid was around 0.35ish if exact values were used from beginning to start as you're supposed to

Anal rape.....

First question in industrial chemistry *shoots myself*

Re: Chem How HARD!!

first question inindustrial chem was more general knowledge, I don't know how it was in the syllabus, I remember doing something similar in year 11, but odd choice of question

 

[LLButters]

Probably the worst exam I've ever done in my life. I'd be happy with a band 4.

 

[umz93]

Honestly mate I think mid 50s scales to b5

Re: Chem How HARD!!

That exam wasn't too bad. That shipwrecks question with the petri dish LOL What idiot puts all the samples in the same dish?

i got that too! woohoo!

 

[brent012]

are you talking about the ostwald process? Cus that was pretty much just about equilibrium - which is in our syllabus

It would have made a lot more sense if they used the Haber process instead since that is something that was in the syllabus and you could also talk about equilibrium/le chateliers.

yes but they didn't want us to spurt out some rote learned stuff
