I think you needed to put about the carbonate and carbon dioxide too

I found it rly easy, I hope i'll get a 9 but dont wanna jinx it. For the ionic equation did u put hydrogen and hydroxyde forms water?
You work out the number of moles and you times it by the avogadro constant. I flopped it in paper 1 and i made sure i revised it

How did everyone do the question with avogadro's constant?

something like 1.5 * 10^21 i believe

what was the answer?

I swear it was 6.92


yeah i got 6.92

I got that
Yup ur right. I flopped it then, i swear thats paper 1 tho

Wasn't it flame photometry

Potassium lilac and sodium yellow??
What did everyone get for how much grams of carbon there is in 100g - i got 82.8 g ?

Pretty sure i got the same

**** I answered 1 nm rather than 100 nm. That's just typical me man

same :frown: at least it was only 1 mark

u needed to put co2 and h20 too cus they don't form ions

as in they're not aqueous

Yes, that is what I put
Do u think i'd get at least 1 mark for writing OH + h?

Grade boundaries will probably be around:
163 - 9
142 - 8
122 - 7 etc.
I think 160 - 9
140 - 8
120 - 7

Yeah so it would be 2H plus and C03 (2- for the charge ) —-> H2O And. CO2 for thé ionic equation

No way that's to high around

I think 165 for a 9
Nah that's to high round about 157
Original post by hehe_x
that was a pretty easy test ngl - grade boundaries are gonna be high
