Practice and Revision - Chemical Reactions and Equations
Let us practise and revise what we learned about chemical reactions and equations. Chemical reactions transform substances into new products
Core concept
A chemical equation represents a reaction using symbols and formulas, with reactants on the left and products on the right of an arrow.
How it works
Balancing equations ensures the number of atoms of each element is equal on both sides, following the law of conservation of mass.
Why it matters
Types of reactions include combination, decomposition, displacement, and double displacement, each with distinct patterns of change.
Key detail
Understanding chemical reactions and equations is fundamental to predicting products and understanding chemical processes in nature and industry.

Quick notes
• Chemical equation: reactants → products.
• Uses symbols, formulas for the reaction.
• Balancing: equal atoms both sides.
• Follows law of conservation of mass.
• Reaction types: combination, decomposition.
• Also displacement, double displacement.
• Each has distinct change patterns.
• Understanding this predicts products, processes.
