This video is the final preparation session I made for my Year 13 chemists ahead of their first exam for AQA A-level Chemistry (7405 specification). Be warned that - particularly for the calculations - I've had to skim over some details FAST because there's just too much to cram in otherwise. All of these slides are taken from full-length videos elsewhere in the channel, so let me know if there's something you need explaining more fully and I can send you the link.
If you found this helpful and want to support the channel, you can "buy me a coffee" buymeacoffee.c...
