bruh that gives more incomplete combustion

anyway guys let's make the most of today and start studying some physics oops I barely know anything from doing chem the past few weeks

like I guess the esterification knowledge could still be partially used for the last question explaining the reaction conditions like I did but it was tad too overkill even for the 7 marker and the response felt really out of balance with the idk 2 pages of esterification thing

and the other half the time we were trying to write practicals up in such a way as to get the "A" grade which barely any of us got in the end people in our class would profoundly relate to this

not the person u asked but I attend one of those 2 listed schools and half the time we literally just did practicals

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

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

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

it was probably 1 equation nvm

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

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

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...

yeah that and the sulfur trioxide reaction with calcium oxide

I also did the quadratic formula method just to make sure the answer agrees with the "estimated" one (by a lot of decimal points), so probably no chance that will lose a mark (assuming of course you set out the quadratic equation properly idk) they'll probably be looking more to see if people...

yeah whichever way around it was oops

like ideally you would talk about both, like defining why the conductometric titration occurs (due to moving mobile charges etc) and explain why it's the shape it is (like u have ions in solution at first making good conductivity, then reduces due to neutralisation of hydronium and hydroxide...

sup people for the aluminium hydroxide question, could we just assume the thing just dissociates completely into al3+ and OH-, because there's like no ksp value? also for the oxidation you could literally just put acidified dichromate which should turn the orange Cr2O7(2-) into green Cr(3+)

Basically, you realise that i) and ii) look quite similar, so you're tempted to take a "cos inverse" of i) to get some relationship of x_0 and x_0-a. However, obviously you can't do this without justification, but you can rigorise it as follows: u have cos(A)-cos(B)=-2sin(A+B /2)sin(A-B /2), and...

WOoOoWwowowoww someone GOT 80????!?!?!?! ok jokes aside, sup guys I'm "englishessayssuck" (mirroring my then-profound disdain for writing english essays like 3 years ago) and my student code for the bos trials was 3705 (so yeah I got the 80). Anyway so yeah I personally found the Bos trials...
