Complete Topic 1e: Chemical Formula Edexcel IGCSE Chemistry 9–1 (14 lessons / 168 slides)

Bundle of 14 fully planned lessons and resources for Topic 1e Chemical Formula & Equations Edexcel IGCSE 9–1 Double/Separate Chemistry.

Checklist, key terms, definitions, tech guide, revision PowerPoint, coursebook questions and answers included. Perfect for new and experienced teachers, this resource provides an authentic, ready-to-teach unit requiring no additional preparation. All lessons are contained in one PowerPoint with a consistent, clear structure.

Lessons & Key Content:

1. Balancing Chemical Equations – conservation of mass, atom counting, balancing with coefficients.

2. Ar, Mr & Formula Calculations – definitions, calculating formula masses, guided examples.

3. Moles & Mass Calculations – using n=m/Mr, rearranging equations, exam-style practice.

4. Empirical & Molecular Formula – calculating empirical and molecular formulae from mass/percentage data.

5. Core Practical: Magnesium Oxide – method, sources of error, empirical formula from mass change.

6. Copper Oxide & Hydrated Salts – reduction, waters of crystallisation, empirical/molecular formula linkage.

7. Reacting Masses – using mole ratios to calculate reactant/product masses.

8. Percentage Yield – theoretical vs actual yield, calculating % yield, interpreting low yields.

9. (Separate Chemistry) Concentration, Gas Volumes & Titration – concentration (g/dm³ & mol/dm³), gas volumes, full titration method & calculations.

Each lesson includes starter slides with title, learning goals and tasks, along with key terms, bolded explanations, and content checked against the specification and examination papers. Core practicals or key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks, blookets and quizzes. The PowerPoint features click-in animations, embedded video links, model questions and answers, and coursebook tasks to support strong conceptual understanding. Plenaries link back to learning goals. A technician guide and full lesson list appear on Slide 2 for easy planning.

Notes:
Slide 1 is repeated for TES display purposes.
Lesson starter slide background is black but PowerPoint colour schemes vary throughout.
Separate Chemistry content is clearly marked and distinguished from Double Award content
