Chemical Reactions -key concepts – student guide 9 MAIS
Key Concept
1. The properties of materials in terms of their
constituent particles and forces holding them
together.
2. Construct and use atomic symbols and balanced
equations to summarise chemical equations eg;
neutralization, precipitation and combustion.
3. The sustainable management of a resource.
4. Chemical change in terms of energy.
Priority 1
2.1: Ions – cations and anions, ionic formulae
Molecules – covalent bonds, naming
Solutions – solvent, solute, concentration, solubility curves
2.2 Chemical Reactions:
Physical and chemical change – characteristics, types,
exothermic and endothermic reactions.
Chemical Equations – word and symbol, balancing equations
2.3 Reaction Types: combination, decomposition,
precipitation, combustion, neutralisation and displacement.
Solubility
2.4: Acids and Bases – properties, pH, chemical reactions,
strong and weak acids, indicators.
