What did you guys get for the mass of iodide or something like that?
This paper so sh*t
Count on edexcel to create a unit 2 exam with hardly any unit 2 in it

i got 117. something grams as the answer

What did you write for the product of water with Cl2O7 .
And in the mcq which gave a peak at m/e value 31


i wrote the product as Cl2O8H2
Paper was meh.Will probably get in 50s i.e C if the boundaries are similar to jan.

First one was 120, shape is trigonal planar.

Next one is a tetrahedral shape with an angle of 107 degrees.

Jinx! its pyramidal not tetrahedral

are you sure from the second one?
what did you get the shape? similar to ammonia?

Darn, you're right. I just checked, it's supposed to be trigonal pyramidal.

The angles are correct


what did you get for the mass of the Iodine?
and the question about the spectrum in MCQ
what about the equations i think i did them all wrong:frown:

I don't remember what I wrote for the mcq, and the mass of iodine I got 114.2 g
What was the answer to the first question about molecular peaks?
And is ketone that doesn't change the color of sodium dichromate (VI)?
And two molecules that would give a peak at 29?

What were the answers to the Multiple Choice Questions:

1. About how many peaks 1,2 dichloroethane had - I wrote 3 but not sure.
2. How many moles of Sodium Sulfate reacted - I wrote 1.00 mol but I'm pretty sure I'm wrong due to the wrong method I think I used.

Also the question that asked to draw the structure of ClO7 - how many marks was that?

Damn that was quite a hard exam! :s-smilie:
