like I used a lot of space to properly define the bronsted lowry theory (and all the acid and conjugate base stuff), had an example of both, used the NH4Cl as an example of a Bronsted Lowry reaction (which isn't arrhenius, thus generalising it) and also the disadvantages as per above (and of course the assessment statement)
used some extra booklets to fit stuff in lol

But they only asked for one right? Double checking lol

yee it's fine. a chem teacher at my school just loves equations and said that there can never be too many haha. allg!

Top school chem teachers amirite

I thought it wouldn't be a bad idea to add some more detail to my response while I was at it, but yeah they only really asked for one (or two? was that a different q?) equation/s

they only asked for one eq (to ur above post). lmao u truly are right but can't say our science faculty is too top-notch though.

i should really go study physics.

Oh crap. Duuuuude, if it’s two I’m screwed, I only did one! Noooo

oh well I was banking on them setting a Cycasin question today so that I could troll and draw the structural formula

same xd

You reckon I’ll get a 4/5 if I mentioned all the stuff I said before but forgot another equation? I’m actually panicking rn, was it actually 2????

it was probably 1 equation nvm

im quite positive it's one equation!!! i replied to u above. don't panic!!!

Haha. I memorised so much for aboriginal stuff after what I heard bio pulled, everything from methyl salicilates to pigs foot leaf juice and what not to cute stonefish and stingray stings and alkaloids in clay and ochre to neutralise excess stomach acid but NOTHING. I’m SO ANNOYED

I just want a band 6 lmao

 

[englishessayssuck]

I just want a band 6 lmao

dw you'll def band 6, and soz if I caused any confusion

I'm actually really surprised that there was no ATSI question. My teacher was telling us the whole year of how an ATSI question will pop up

ATSI?

also
where were the questions on soap/detergents, bioethanol and biodiesel
or any of those polymers
or any of those colours of precipitation reactions or flame tests
or anything

bro i literally memorised the chemical formulae for all those bloody detergents with their long af carbon chains. heck.

ikr all those sodium stearates and sulfonate/ammonium heads and those nonionic thingos

I know!!!! Friggin memorised the whole process of transesterification of biodiesel, it’s gravity density separation techniques and how it’s 9% less efficient energy per volume than diesel!!! Polymers was the most time I spent memorising, the theory that was included was the theory I spent the least time memorising

ATSI?

Aboriginal and Torres Strait Islander

Aboriginal and Torres Strait Islander

Oh right. Never heard that acronym
