Summary Notes from an A student including equations, diagrams, definitions, required practicals and examples of: - relative atomic mass - writing ionic equations - amount of substance (moles, molar gas volume) - hydrated salts - concentration and diluted concentration - standard solution - ideal gas equation - avogadro's constant - percentage yield - atom economy - acids and bases - titrations - percentage uncertainty - redox reactions and equations

This workbook is designed to help you actively recall the key OCR A organic mechanisms by filling in the blanks yourself. Instead of passive revision, you’ll complete each mechanism stage — reactants, intermediates, products, and arrows — before checking against the answer booklet (sold separately). Fill-in-the-blanks format – forces active recall and deeper memory retention Covers OCR A organic mechanisms (nucleophilic substitution, electrophilic addition, elimination, etc.) Ori...

This booklet provides the fully worked answers to the Organic Mechanisms Fill-in-the-Blanks Workbook. It can be used on its own as a clear set of revision notes, or alongside the workbook for self-testing and active recall practice. Fully annotated answers – step-by-step arrows, intermediates, and explanations Covers all OCR A organic mechanisms (nucleophilic substitution, electrophilic addition, elimination, radical substitution, etc.) Clear diagrams & worked stages – perfect as qui...

These OCR A A-level Chemistry revision booklets cover Paper 1 content: Module 3 (Periodic Table & Energy) and Module 5 (Physical Chemistry & Transition Elements). They are written in a question-and-answer format to ensure active recall and strengthen exam technique. While primarily designed for Paper 1, these notes are also highly useful for Paper 3 (synoptic assessment), since Paper 3 draws heavily on Modules 3 and 5. The material is also relevant to AQA and Edexcel Chemistry, which share si...
