When the spatial arrangement of atoms of a molecule of a substance changes it results in the formation of a new substance with different properties.
Explanation:
- A chemical change is defined as the change when the chemical composition of the substance changes and results in the formation of a new substance as a product.
- During this change, a change in the spatial arrangement of the atoms of the substance(s) or the molecules occurs which results in a chemical change.
- Properties of the newly formed substance are different.
- When existing bonds are broken and new chemical bonds are formed chemical change occurs.
- For example: Rusting of iron : [tex]4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)[/tex]
So, according to the definition of chemical change can also be written:
When the spatial arrangement of atoms of a molecule of a substance changes it results in the formation of a new substance with different properties.
