Are you sure this is not a simple class practical rather than an exam practical?

No it's definitely an exam as I have to come in to school on an inset day.

If it's anything like OCR, you'll get a practical on a titration, and/or one on enthalpy.

There are usually 4 q's in the edexcel unit 3 practical on:

Tritration
Salt Analysis
Heat enthalpy change

and a question in which u've to devise an experiment.

The practical is open book so you can take all your notes , books and even past papers with you.

The prac paper in AS isn't that hard, a few tests and a titration. You should've practiced all the techniques in school by now and seen what happens and what the practical exam will be like. You can take notes in with you though.

One question though, how have you only just realised you've got the exam next week? Have you missed a lot of school or something (or have you been asleep through every lesson?! ) ? Dont want to intrude or anything and apologies if I have but it seems a bit weird that it's sprung onto you today.

lol, you're a bit slow. This thread is quite old.
I got an A anyway so it doesn't matter now.
If you think I fall asleep in my favourite subject then you are mistaken.

When it says the bond angle is 109° 28' what does the 28' mean? Bond length?

And also, if, say, BeCl2 is a linear molecule, how do you describe molecules like water which are bent like that? V-shaped??

yes v-shaped, although it's better to say bent linear.
