Hi, u know the born haber cycle in this years exam that was worth 9 marks, well i thikn i got quite a bit of it wrong because i used "2Cl-" instead of only one "Cl-" in the diagrams, and hecne i must have got the calculation wrong for not halving one of the values. Does this mean i lose all the marks or will i still get a couple for the rest of the diagram, and also are the consequence marks for later questions?

Thanks,

Kaz.

dunno about the marks for the diagram, but if you got a wrong value for the enthalphy change and carried it forward, you won't lose marks in the next question
