Two things struck me when I saw this photo. Firstly, Ben appears to have had too much shandy. Secondly, George looks like he could have done with a bit more. Thanks to Cheryl for sending the picture in.
All the best in the forthcoming exams. It has been a pleasure to share your company over the last two years.

CHEM2 papers
The CHEM2 paper is next Monday and although you have probably had plenty of practise already, you may feel the need for some further fine tuning with past paper questions. Knock yourself out with these.
They are old syllabus questions, which means that the CHM2 papers represent mostly the thermodynamics and inorganic chemistry stuff, and the CHM3 papers are all your organic chemistry work. There may be the odd thing that is now taught as part of CHEM1, like the content on oil or structural isomerism, but most of the following papers will help you prepare fully for next week.

explosion of the month 7
According to the blurb accompanying the original video on YouTube, this blast was much larger than the navy mine clearance team intended. The black dust that appeared a few seconds after the initial explosion was the remnants of a sunk Second World War vessel caught up in the explosion, it is claimed. With that size of blast it's a wonder we didn't see any more exploding whales like last month.

CHEM5 papers
If you scroll down this post a bit you'll find some papers and mark schemes for your revision, although hopefully you'll have had many of the answers fully explained in class by now. Just remember that there are some synoptic elements to CHEM5, meaning that the board can ask you anything from earlier modules which have a link to the new content studied in module 5.
As far as I can see, the most likely subject areas to crop up again are:
Thermodynamics
· Calorimetry (from CHEM2)
· Equilibria and Le Chatelier (CHEM2)
Redox Equilibria and cells
· Redox behaviour of halogens (CHEM2)
Periodicity
· Physical trends in period 3, melting point, 1st ionization energy etc. (CHEM1)
· Solubility trends of sulphates/hydroxides (CHEM1)
· Extraction of aluminium (CHEM2)
Transition Metals
· Electron configuration (CHEM1)
· Shapes of molecules (CHEM1)
· Extraction of metals, iron, aluminium, titanium (CHEM2)
At any point they could very easily throw in a pV=nRT calculation as well, so make sure you know the standard units.

Older CHM5 papers can be found further down. Just be careful to ignore any organic chemistry or other module 4 based questions on the old syllabus papers. However, if you are resitting the CHEM4 paper then there will be some useful stuff on here for you to try on equilibria and acid calculations, as well as the essential organic stuff.
If you need any more old CHM5 papers then send me a quick email and I'll let see what I can do.
