Answer : The type of chemical bond form in
molecule is covalent bond.
Step-by-step explanation:
Ionic bond : It is defined as the bond that is formed by complete transfer of electrons from one atom to another atom.
That means, the atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.
The ionic bond is usually formed between a metal and a non-metal.
Covalent bond : It is defined as the bond which is formed when sharing of electrons takes place between the atoms.
This is usually formed between two non-metals.
The given reaction is:

In this reaction, the reactant is
molecule.
In
molecule, oxygen is non-metal. So, two oxygen atom will form a covalent bond by the sharing of four electrons.
Hence, the type of chemical bond form in
molecule is covalent bond.
