I feel like the first paper went super well, and with my CA (A*), I hope I'll get an A* overall. This paper actually went rather well, so hopefully an A*. :smile:
Guys litearlly i have been the smartest student in my class and throughout the coursewrk working days iput 100%. To achieve the a star. But however that wasnt the case and i got 37 out of 48. I so pissed. And my chem teacher is a idiot aswell so... do u think with postal moderation these cw mark can be put up. For me to acheive my stars. Becuase i certanily think i got both stars on both paper?.

If yours was sent off for moderation then yes it is definitely a possibility :redface:. If 37 is an a, you shows still get an a* if your tests were both good a*s anyways :tongue:

Dude, if you think you've gotten A*'s on both papers, chances are you're going to end up with an A* overall. Don't sweat it. :smile:

You may have needed to write about the fact that hydrogen is bubbled through the oil too in order to achieve both marks. I'm sure you at least got one, if not two for writing what you've written above. :smile:
Urmm and the displacement 6 marker. The word equation was iron plus copper sulfate makes iron sulfate and copper. And crap i forgot to include tjose half equations fml

You can still probably get a good mark even without the half equations, and thanks for letting me know I got the equation the wrong way round :smile:

Good luck for physics on wednesday :smile:

Thank you :smile: I will amend my mark scheme :smile:
I'm not sure looking at mark schemes really does my confidence very good! :frown: Good luck for Physics on Wednesday everyone as well!
C6 finished - only Section D left :smile:

How did you get 1920? Just interested cause I had no idea :smile:
Where's section D???
Welp, after looking at the mark scheme, I feel a tad less confident, hopefully 46 will be an A! But good luck for Physics everyone!
It was 1920 cm3 for the volume of gas at room temperature
