These reactions are essential for life, as they allow us to convert food into energy, build new molecules, and eliminate waste products.
- Reactants and products
In a chemical reaction, the atoms and molecules that are present at the beginning of the reaction are called the reactants. The atoms and molecules that are formed at the end of the reaction are called the products. The reactants and products are always different substances.
- Chemical bonds
Chemical reactions involve the breaking and forming of chemical bonds. Chemical bonds are the forces that hold atoms and molecules together. There are many different types of chemical bonds, and the type of bond that is formed depends on the atoms involved.
- Energy
Chemical reactions can release or absorb energy. The energy that is released or absorbed is called the heat of reaction. The heat of reaction can be used to do work, such as heating a house or powering a car.
- Examples
Examples of chemical reactions include:
- The burning of wood
- The rusting of iron
- The digestion of food
- The photosynthesis of plants

Basis of all physical properties
Examples of atoms and molecules are the basis of all physical properties. The physical properties of a substance are the properties that can be observed without changing the substance's chemical composition. These properties include things like color, density, melting point, and boiling point.
The physical properties of a substance are determined by the atoms and molecules that make up the substance. For example, the density of a substance is determined by the mass of the atoms and molecules in a given volume of the substance. The melting point of a substance is determined by the strength of the bonds between the atoms and molecules in the substance. The boiling point of a substance is determined by the strength of the bonds between the atoms and molecules in the substance and the intermolecular forces between the molecules.
Understanding the connection between examples of atoms and molecules and the physical properties of substances is important for many reasons. For example, this understanding can be used to design new materials with specific properties. It can also be used to understand the behavior of substances in different environments.
