theyll give you the mark for brown precipitate, but ignore the red, so you should get the mark!

I didn't mention solution atall just put colour, and like you said colour is key word. So maybe lose one mark?

If they were to give you any marks it would be two. But in mark schemes it says usually that you need to mention precipitate or some kind of alternative.

For the Iron (2) and iron (3) question I put the colour of the precipitate bt not the word precipitate. Will I still get the mark?

Gonna be annoying if we don't get the 2 marks for that question...

What mark do you think is good to get in this paper?

I did the same thing!! I hope we get the marks. Benefit of the doubt?

Who knows? Probably not, though I hope so! The mark scheme will probably say: green precipitate...

Eh well. Maybe ECF? Or does that only apply for calculations?

I would say if you were aiming for an A*, and you did decently in the last paper, a good mark to get would be anything above 40 :biggrin:

Hey guys i found this exam easy I think anyways you know the one where you had to write down the equation for incomplete combustion i put CO+C+H20+CO2 is that right obviously i balanced it. also on the last question i got 66000cm3 its wrong i know but would i get at least one mark for stating that moles=volume*24000 or nah. TY TO THE PERSON WHO MADE THIS MARKSCHEME X

I am doing physics. With regards to chemistry the average boundary is 121 for an A and max was 128 so I don't sew the boundaries being over 130 for A and 150 for A*

On the dot and cross diagram question I only put the charges and not the transferred electrons. Out of 3 how many marks would I get?

Do you think they'll accept orange in place of red, the question wasn't that clear

I put orange and I think its better, because red represents acid not neutral

Yeah I put that too, and so did everyone else from my school who I talked to. In fact, even yellow would be a more appropriate answer than red in that instance.
