Chemical Formula Writing & Chemical Equations (Perfect for Exams)

Course Overview

The Chemical Formula Writing & Chemical Equations (Perfect for Exams) course gives learners a clear, step-by-step, exam-focused mastery of how to write accurate chemical formulae (including radicals / polyatomic ions) and how to write and balance chemical equations using mark-scheme-ready rules.

It is designed for IGCSE and O Level Chemistry learners who want speed, accuracy, and confidence in high-frequency exam skills. Using structured explanations, worked examples, exam techniques, interactive quizzes, and high-quality LearnStalk explainer videos, learners will develop fast recall, correct application, and consistent accuracy—so they can solve questions under exam pressure without guesswork.

What You Will Learn

• Write correct chemical formulae using valency and charge balance, including compounds with radicals.
• Apply criss-cross / charge balancing methods accurately for ionic compounds.
• Write clear word and symbol equations with correct structure and naming.
• Balance equations using reliable atom-count methods (no guesswork).
• Differentiate empirical vs molecular formula in exam questions.
• Master common exam-tested ions and compounds with correct bracket usage.
• Use naming patterns and valencies to predict formulae quickly.

Why This Course Matters

Many learners lose marks not because they don’t understand Chemistry—but because they make mistakes in formula writing and equation balancing.

These are high-frequency exam skills tested across multiple topics.

This course gives you a repeatable rule system:
• Charges must balance
• Subscripts must simplify
• Equations must conserve atoms

Once you master this system, your answers become fast, accurate, and consistent.
