OCR A Chemistry F322 Chains, Energy and Resources Thu 19 Jan 2012

sure!!! how did u find bio by the way heard many people said difficult

the one that has the weakest bonds, the one that is lowest in the period table.. i think its iodoprpane and it would colour change much faster. same mass of the product and in a water bath? add NaOH, silver nitrate?

Look closer at the names of the two halogenalkanes and how could it effect the hyrolosis.

Hinto use bond enthalpies when comparing the halogen alkanes

Hey

What was so different about the f321 paper? I didn't take it i'm just interested.

Haha hey! It seems we do the same exam boards, and flopped the same modules Lool!

Ah how's your revision going? Mines actually terrible, I don't know what to do!!

Haha yeah, I scraped a C in the June paper

Revision was hard yesterday as I was quite tired from Biology so hopefully get an effective 3-4 hours done now

Haha doing exacthe same thing as you, had a good nights sleep yesterday (well sort of) and now it's revisions time!

How you revising? From textbook or just banging out papers?

I'm going through a few stuff that I wanted to cover last night, almost done so yeah will do past papers in about 10 minutes. You?

My school gave us a huge pack with al the questions like from the beginning of time, I'm just ploughing my way through that, but u haven't even looked at green chemistry yet >.<

what time is the exam?

Afternoon

I got a big selection of past papers too, I'm going through the official ones then will do a few of the old spec papers for further testing and see if I need to learn anything yet.

What's green chemistry about - is it that
-ozone depletion
-minimising damage
-the hsw stuff?

Yep all that stuff and the carbon recapture stuff too!! It's only like 8pages but there's quite a lot of info -_-
