1. Please tell me there was no titration calculation question ?
2. (Original post by eve_4342)
What did you draw :0 I drew what it said in the picture XD Yeah, only 1 mark - be positive!
I think you have gotten it right if it was on the question I don't even know the exact name of the thing I worte but it's thi weird tub thing but yeah it' ok 1 mark

Nope (surprisingly) There was a question were you had to take the average titre

Ignore that possibility :-)
haha yeah but what did you do to get it I saw they divided 1 by 100 so did the same for 24
5. I also got 0.24, hopefully that's right

Ive got the question booklet with me and circled the answer as i went along
Aha oka, I thought you had an insane memory

I done this:
1 mole --- 1 = 24 litres
0.01 moles = 24*0.01/1

0.24 litres.

cool as long as it's right

I really didn't do that! I saw the equation and was like 1m = 24 or 3m = 72.
Then 2/2 x 0.01 = 0.01 al moles and then 72/2 x 0.01 = 0.36

Haha oh sh*t XD

You're method could be right. Nobody knows the real answer yet But please god let it be 0.24 litres :P
12. Lol i wish

That could still be right

I hope for me!!!!

I hope!
16. For the last using your knowledge q what did everyone put down?
17. I'm pretty sure that 0.36 litres is right as the balanced equation above the question showed 2Al to 3H2
18. For the strontium question where it asked you to talk about it's chemistry what did everyone say? I talked about it's:

It's valency and how it's in group 2
Then it's Atomic Number and then I explained how it represents the number of protons and electrons.
Talked about how it's a metal and has metallic bonding.
Talked about how it can conduct electricity and briefly explained why.
Then I ended it off with its relative atomic mass and what it means for its isotopes.

I only now just remembered a very easy one I could of talked about: It's flame colour -_- (Facepalm)
19. (Original post by studyranger)
For the last using your knowledge q what did everyone put down?
Boil caputure the gas, add lime water
couht the bubbles
Hold damp pH paper over the tube and see how red it goes as CO2 is acidic
Weigh out 100g abd then measure the volume, as bubble take up space

I wrote it in more detail in the exam lol
20. What did everyone get for the what type of reaction is it at beaker B and the other reaction one?
