Chemistry Enthalpy Changes Practical Part II

Nice one Robyn, thanks for typing it all up ;)

I'll just point out that if you (You being anyone not me and Robyn) are thinking about taking Chem for A-level, this is the kind of thing you will be doing.

Another thing --> When you do an experiment like this, make sure you have a good stopclock! When we added the HCl to the NaOH we were meant to set it going.. Robyn was meant to set the stop-clock going to record the temp @ 5-sec intervals.
Well by the time she got it started the reaction was already over (It was the stopwatch, she's not that bad ;) ) and our results looked something like this..

12.4
12.4
12.4
12.4
...
18.4
18.4.. Etc

We ended up having to make up some results off the top of our heads.. It's all fun!

Grats on your Maths result Wob, I'll egt mine back soon, I don;t think I did as well..
Your essay.. *Cough* Google *Cough* I'm sure something'll come up

My electronics today we did not much.. Basic D-type flip-flop up/down 4-bit counters (Comment if you wwant it explained!)
Maths.. More Calculus.. But we're taking it easy after the test
Computing --> I need to think about my project what I'm going to do.. Probably a database for a hotel, with room reservations, staff, customers etc.. Will be fun

We've finally got round to posting some! Hope we can keep it up
