Chemical reactions are processes in which one or more substances (reactants) are converted into different substances (products) through the breaking and forming of chemical bonds. These reactions involve the rearrangement of atoms and the transfer of energy, resulting in the formation of new substances with different properties than the original reactants. Chemical reactions can be classified into different types, such as synthesis, decomposition, combustion, single replacement, and double replacement reactions.

Chemical Reactions
A chemical reaction is a process that involves the rearrangement of the atoms of reactants to form different substances, called products. These reactions follow chemical rules and involve the breaking and forming of chemical bonds.
Key Features of Chemical Reactions:
- Reactants: Substances that enter the reaction.
- Products: Substances that are formed in the reaction.
- Chemical Bonds: The forces that hold atoms together in molecules.
- Conservation of Mass: Mass is neither created nor destroyed in a chemical reaction.
- Energy Release or Absorption: Reactions can release energy (exothermic) or absorb energy (endothermic).
Types of Chemical Reactions:
- Combination Reactions: Reactants combine to form a single product.
- Decomposition Reactions: A single reactant breaks down into two or more products.
- Single-Displacement Reactions: One element replaces another in a compound.
- Double-Displacement Reactions: Two compounds exchange ions.
- Neutralization Reactions: Acid and base react to form salt and water.
- Oxidation-Reduction Reactions: Electrons are transferred between reactants.
Representation of Chemical Reactions:
Chemical reactions are represented using chemical equations, which describe the reactants and products involved. For example:
```
2H2 + O2 → 2H2O
```
This equation represents the combination reaction between hydrogen (H2) and oxygen (O2) to form water (H2O).
Importance of Chemical Reactions:
- Chemical reactions are essential for life, as they power biological processes and provide the nutrients we need.
- They are used in industries to produce countless materials, such as medicines, plastics, and fuels.
- Understanding chemical reactions helps us comprehend the natural world and develop new technologies.
