Yeah im with u, in my trial i said it was a cataylist and got marked wrong lolnadz001 said:i totally agree with yiou the clorine is seen as an iniatiare for it breaks the ozone bond. a catayst lower rate of reaction it does play an actual role
For 14 I put C (I don't even know if that's right?) because I thought B was explaining AES?mat2154 said:pretty sure 18168 is correct
just wondering if someone could clear up the answers to the multiple choice questions:
1. A
2. D
3. B
4. C
5. D
6. C
7. D
8. C
9. A
10. C
11. B
12. A
13. A
14. B
15. C,B
thanks
Yes it's a catalyst.. if you google "catalyst in breaking down of ozone" you'll see a lot of sites which agree.fatemjay said:if Cl was an initiator it wouldnt be reformed.
they cant mark catalyst wrong, as they base it on textbooks - if one textbook says that its a catalyst they cannot mark catalyst wrong
EDIT: the answer to question 14 was (D)
Yay i got all the same except for 14 which i put as D),,, i think we both got 9 wrong cause i found out after that Sodium Citrate is citric ACID with Na and i reckon the correct one is D cause CL is weak conjugate base HCL :mad1:mat2154 said:pretty sure 18168 is correct

Yeah to be honest I thought it was an initiator, cause a catalyst does not play a part in the chemical reaction.Bank$ said:Yeah im with u, in my trial i said it was a cataylist and got marked wrong lol
ummm i got like 600ppm for the Ag question,,, haha think of it like this if we all wrong we all get scalled up

No 9 is A because Ammonium Chloride is an acidic saltBank$ said:Yay i got all the same except for 14 which i put as D),,, i think we both got 9 wrong cause i found out after that Sodium Citrate is citric ACID with Na and i reckon the correct one is D cause CL is weak conjugate base HCL :mad1:
any 1 remember the precipitate question ? i think i got 3 as Pb solution, 2 as HCL, 1 as Na2CO3 and just deduced the last one
Yes I got 3mLJoshyPutts07 said:yeh i got 18045
..............but then i divided by 1000 coz im like "there is no way that can be correct", oopsies!............TRUST THE CALCULATOR NOT YOUR FRIKIN SENSE haha
and i got 2.3L for SO2 question
oh and did you people get 3mL for the KOH neutralisation?
I thought it was C too... I honestly thought the flame test wouldn't be enough to excite the electrons but I just realised it would be for most of them so it should be D.. damn!Pyros89 said:Yeah to be honest I thought it was an initiator, cause a catalyst does not play a part in the chemical reaction.
I though 14. was C, but Im prob wrong
But its called atomic absorption spectroscopyMartyno1 said:I thought it was C too... I honestly thought the flame test wouldn't be enough to excite the electrons but I just realised it would be for most of them so it should be D.. damn!
ohh gud then im safe lol damm now im definate i got the ppm one wrong i hope they mark like maths and c that i had the right working out lolMartyno1 said:No 9 is A because Ammonium Chloride is an acidic salt
