Tbh as far as I can think of the a few 1 markers. The first question with the mean and the anomalous data (if that proves to be correct), the question asking the number of electrons in iodines outer shell, me be silly tried to count them instead of realising halogen is a halogen. And the asking for the ionic equation... had no idea what an ionic equation was so I put (Na+OH-)+(H+Cl-) ---> (Na+Cl-) + (H+OH-), I then wrote the worded equation below.
I think the answer was just H+ + OH- --> H2O
Ahhhh right that shouldnt be tooooooo bad. I think I lost one mark for saying you heat the copper oxide with the acid to help it dissolve quicker and maybe one mark on the 6 marker because examiners probably wont give too many full marks. And I probably lost one mark somewhere else just as a normal candidate would.
Dont be worried, you probably will still come out with an a*
Yeh I know, I checked when I got home aha, not to bothered about it...
Its only one mark but the reverse reaction symbol was important because of the reaction type (dont know what that means but hey!) my teacher can be confuddling at times!
