I forgot but wasn't it KMnO4?

It was K2SO4

 

[Zaki ali asghar]

how much are you guys expecting

 

[amina1300]

It was K2SO4

Oh yes hwd u get the conc?

 

[Zaki ali asghar]

the mass was 1.74 and volume 5cm^3 right?

 

[anastasia grey113]

i hope the threshold isn't high enuf n is somewhere around 21 or 22
how hard did u guys find it?

man it wasn't hard but i feel like i gave some vague answers so don't really know

 

[anastasia grey113]

We were post to find the no. of moles.
I also got the wrong answer I got 5x10^-3 cuz of silly mistake -_-
we were post to convert the volume 0.05cm3 into dm3 and had to multiply it with conc.

 

[amina1300]

Yeah tru^ didn't even ask for any diagrams this time

 

[anastasia grey113]

man it wasn't hard but i feel like i gave some vague answers so don't really know

yh same
idk it wasnt too hard but idk it was just wasnt like the same old papers ive attempted

 

[anastasia grey113]

yh thaz right

I used the moles ratio 1:1 and did something how much marks was this worth

I got an A in chem
wbu?

 

[anastasia grey113]

I us

just 1
dw lol

Same here. How much are needed for an A* realistically? If you have around 100 in AS.

 

[anastasia grey113]

isnt it weird?
they literally allotted 10 marks just for filling in the table, drawing a graph and finding the gradient

well our threshold was 88 in AS so i think it should be around 185 in A2.
I guess 85 in total?

 

[Zaki ali asghar]

was the gradient something 0.50?

 

[anastasia grey113]

was the gradient something 0.50?

yh i got 0.515 actually

I got a 17.1 on my gradient WBU?
