all physical changes are reversible and only chemical changes are irreversible.do you agree?give reasons and examples.

Hi,

All chemical changes are not necessarily irreversible.

the reaction between hydrogen and oxygen to form water is an example reversible chemical reaction. The reaction can be represented as:

H₂ + 1/2 O₂→ H₂O
