Oxidation and Reduction |
Combination Reactions:
Decomposition Reactions:
In a decomposition reaction, a single compound breaks down into two or more simpler substances.
These reactions require energy in the form of heat, light, or electricity. Therefore, decomposition reactions come in three forms: thermal breakdown, light breakdown, and electrolysis.
Below are examples of each:
Dissociation Reactions:
Reversible reactions where a molecule dissociates into simpler molecules by heat or light.
Displacement Reactions:
Exothermic and Endothermic Reactions:
Reversible and Irreversible Reactions:
Redox Reactions:
Involve oxidation and reduction as two half-reactions. Examples include fuel combustion, electrochemical processes like sodium hydroxide manufacturing, photosynthesis, food digestion, battery functions, and metal corrosion. These reactions involve both oxidation and reduction processes.
