Guys i want you to grade me please im really worried first exam i worry about i get the apartus and curves right .. and last question first page i wrote cryastallization and to make solvent more solube how know if reaction finished i wrote residue of iron powder and the second point is wrong nvm about it anw i lost a mark about what kind of reaction and a mark on what happens if you mix iodide and silver nitrate qualtative analysis nailed it so did the question about the filter diagram the readings i had no mistakes but last question i wrote to put each iron nail in seperate test tube add water (rusting conditions ) add the inhabitors and compare the results see which one rust and which ones rust faster please how much you think i can get im really worried sorry for troubeling you and reading all this PLZ guys

Im not doin a lot of revision for physics coz I think Im better at it than I am in chemistry....any revision sheets, formula sheets and other key points etc would be greatly appreciated thx

Yeah greatly guyz
Well I think I'm better at chem dude isn't it opposite the thing ur not good at that's wat u focus on ? Lol

I know the thread says chemistry p61 but seriously wat r u guyz doin for physics p3 it's major me freaking out lyk hell

Not worried at ALL about physics. Chemistry is my only weakness..
Phsyics should be easy x)
I'll just go over the past papers I solved and there mark schemes.

Wat if we give u a bad grade will u kill us
Jus kidding inshallah if the curve is Medium then I'll get at least an A cud be an A*

 

[EpicLol]

I checked like all the previous grade thresholds and its usually 42-47 out of 60 for getting an A....so I think Im safe.....

So how many u think u got cut

 

[IGCSE O/L student]

ok for the checking of purity..I wrote melting point??

yeah i wrote melting point too , i think its correct because that is whats written in my notes

yes, dats ryt

 

[Saadiya Ahmed]

I think we had to multiply the points by 10 so the first point would be 4 and so on by this way you will get a straight fixed line and i hope we all get it correct inshallah and good luck

Oh ryt...sry i was toking abt the other graph then...u have to exclude a point in tht ryt?!...
IA we'll pass wid A*'s...x)

Dear, Potasium IODIDE + SILVER NITRATE, isn't that a test of??? It shows yellow precipitate

I wrote rate of reaction decreases coz iodide is less reactive compared to chlorine...
Is tht ryt?!

 

[IGCSE O/L student]

ok wat u wrote for the copper can?

idk if I'm ryt, but I wrote da temp rise wud b less coz sum of da heat wud b absorbed by da copper.
