Re: Current Year 12 Thread Mark VIChemistry:
Paper 1 : What is a catalyst? (2)
My answer: A substance that lowers the activation energy in a reaction by providing an alternative reaction pathway. It isn't itself used up in the reaction.
Answer: It speeds up the reaction without being used.
Paper 2 : What is catalyst (2)
My answer: A substance that speeds up a reaction and isn't used in the reaction
Answer:A substance that lowers the activation energy in a reaction by providing an alternative reaction pathway. It isn't itself used up in the reaction.

1st Paper: Define the standard enthalpy change of combustion.
Me: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions.
Markscheme: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions of 298K and 1atm pressure.
2nd Paper: Define the standard enthalpy change of combustion.
Me: The enthalpy change when one mole of a substance undergoes complete combustion at standard conditions of 298K and 1atm pressure.

Got this from the "Official WJEC Chemistry unit 2 revision guide":
"Polarization of an anion is when a polarisable anion is polarised"
My board is so stupid.
We're just having a rant about Chemistry now.

We will be modelling in LA.
Soz. :/
Muahahah. And I have finished all my oboe grades - unless I do diploma. 
It's fine - you don't have to if you don't want to.
Are you going to do diploma?

Okay.
I don't know - I probably don't have time.
I can't believe in the film of the hunger games, they left out the sleeping bag. It plays such a vital role!

Re: Current Year 12 Thread Mark VIWe do everything in pairs so no. If there is an EMPA I get an assistant. I'm lucky really, it's never caused any problems(Original post by Maths_Lover)
It must be so annoying when you're doing practicals and have to write down your observations.

That is a good point!
Never mind the characters, it's the sleeping bag that should get a starring role.
On another note, my parents really liked my school report. They didn't even pick holes in it this time for the first time ever.
Oh wow - that's handy!(Original post by wcp100)

Re: Current Year 12 Thread Mark VITrue(Original post by Maths_Lover)
Because doing things like that are so much more fun than revision is.
, plus AS physics is boring =/
It's a good thing they think of things like that.
