Hi everyone!

Can anyone of you remember:

Was the last page before the periodic table empty (a blank page) (on the right side)?

What was the last question below the question about concentration in g dm-3?
It was about uncertainity of the burette

Hi everyone!

What was the last question below the question about concentration in g dm-3?
What was the ionic equation for iron filings and copper sulphate?

Also, What did you wrote for M/E values. I think one was 15 and the other was 31
(edited 4 years ago)
Fe2 + CuSO4 = 2Cu + FeSO4

they didn’t ask for any m/e values, they asked for us to draw the ions for those values

Yeah the m/e values were given
for 15 was CH3
and for 31 was CH2OH

Btw what did you write for the lasy part of this question? I think it was about difference between infrared spectrum of cyclobutanol and C4H8O

I wrote that cyclobutanol specteum will have no peak for c-c double bond

Correct

I think you meant/It should be:

Fe + CuSO4 -> FeSO4 + Cu

Was it a calculation? 0.25*2/volume * 100%?

Because I don't remember writing a multiply by two 😨

What did the last question about burette uncertainty ask about?

Anyone?
I think it was the pipette actually because I don't remember multiplying by 2 either!
