    I wrote Sulfur Hexafluoride and then crossed it out and wrote Sulfur Hexafluorine
    I did exactly the same!

    Cl2 wasnt provided, only Cl- ions were given so the Cl2 +Br- reationcoudnt take place
    i was talking about the chlorine and iodine reaction that nott necessary

    only two reactions where needed. bromine water + cl- ions to show chlorine is more reactive (no reaction takes place) Orange
    bromine water + I- ions to show bromine is more reactive than iodine (purple)
    therefore Cl>Br>I in reactivity

    the ionic equation which has been posted is right

    only two reaction needed remember it wanted the minimum amount of reactions
    Really hated this test by the way made so many silly mistakes and paper was a little cheeky, well it is OCR

    its Neon, because it don't form bonds extremely low boiling and its si (larger atomic radius)

    Was the reaction disproportionation?

    Put disproportionation first...then crossed it out and put disproportion:mad:

    Would I lose marks?

    If I said that the mol of Nitrogen atoms

    as 1.699 times 10 to the power of negative -3.

    For the 5 marker.

    I said you would use a minimum of 3 test tubes which is wrong.

    I then said you would add Br2 to 2I- to form 2Br- and I2 thus would become a violet colour.

    I then said you add 2CL- to the Br2(aq) so that you are just left with your orange solution.

    I then said you would add 2CL- to I2(aq) to form a brown solution which is incorrect.

    How many marks out of 5 would I obtain?

    I'm thinking 2/3.

    Okay, I reckon 45-46 for an A, small things catch you out. I was so happy at seeing SF6 I immediately wrote octahedral without reading the question LOOOL.
