Competency Focused Questions: Chemical Reactions & Equations
A compact, exam-oriented set of CFQs that build concept clarity, application, and analysis for Chemical Reactions and Equations.
Key Competencies
Concept Understanding
- Identify reactants/products; write and balance equations.
- Recognize evidence of reaction: gas, colour change, precipitate, temperature change.
Application & Analysis
- Classify reactions (combination, decomposition, displacement, double displacement, redox, neutralisation).
- Relate reactions to daily life—corrosion, respiration, rancidity, tarnish.
Quick Exam Tips
- Always balance equations neatly.
- Underline states: (s), (l), (g), (aq).
- Relate to real-life applications.
