Chemical reactions can be categorized into combination reactions, composition reactions, and displacement reactions based on how elements interact to form new products with varying attraction forces. Each type of reaction involves different processes and outcomes, such as the creation of water molecules from hydrogen and oxygen, breaking down compounds into different atoms, and displacement reactions where elements replace each other based on attraction forces.
Insights
- Chemical reactions can be categorized into combination reactions, where elements combine to form new products, and composition reactions, where compounds break down into different atoms.
- Displacement reactions showcase the phenomenon of elements with stronger attraction forces replacing those with weaker forces, exemplified by zinc displacing copper in a reaction with copper sulphate.

Types of Chemical Reactions Explained
- Chemical reactions involve different types, starting with combination reactions where two elements combine to form a new product, like hydrogen reacting with oxygen to create water molecules.
- Composition reactions involve breaking down compounds into different atoms, contrasting combination reactions where elements combine.
- Displacement reactions occur when elements with higher attraction forces replace those with lower attraction forces, such as zinc displacing copper in a reaction with copper sulphate.
