    I got

    Chromatography for the seperation question but a lot of people said fractional distillation.

    Cu3H2C2O8

    0.451g
    1065000 for the mass
    49.3% (this is deffo right)
    And first method because 4 miles of phosphoric acid is produced instead of 2 and also, no second product is produced in the first method. However, you can also say second method because it's a one step reaction.
    how did you get 49.3% i got 15 or 16 something

    What did everyobe write for the similarities and differences question. I put that the isoptopes abundance is the same as a similarity but 2+ions are produced as a difference. No idea if thats right
    Same, that was the only nasty question

    Yes I also got 49.3 and 0.451m3 but everyone got 0.113 so I think we did it wrong somehow?

    What did you guys get for the similarities and differences?

    I got similarity of That their isotopes
    And differences is that it forms +2 ion and not a +1

    yeah i wrote that and added so a different m/z ratio

    I guess it's 0.113 and 0.451 is wrong and I got that too
