Grade 9 Notes for AQA GCSE Chemistry - Unit 4 - Chemical Changes

These are comprehensive notes, fully covering the fourth unit of the AQA GCSE Chemistry specification. They are divided into the subsections of the specification, and cover all of the information required to achieve a grade 9 in the exam.
My name is Caleb, and I am currently in year 13 at Colchester Royal Grammar School, one of the UK’s highest achieving institutions. I study A-levels in Biology, Chemistry, Maths, Further Maths and Economics, and am predicted A* in all 5 subjects. These notes were used throughout years 10 and 11 to help me regularly achieve top grade 9s in my chemistry exams at school, and therefore will allow you to do the same. I also used them to revise for my final chemistry GCSE, where I achieved 94% and a grade 9. If you have any enquiries about the notes for any reason, feel free to contact me at calebcol@crgs.co.uk.
