The bond between the 2 Cl atoms in a Cl₂ molecule is a covalent bond.
to break this covalent bond, energy is required.
when new bonds form, energy is released as the bond formation makes the molecule stable. molecules with low energy levels are usually stable.
To break the covalent bond, energy is required in other words energy is absorbed.
therefore to break the covalent bond in Cl₂ molecule
1)energy is absorbed
If the item or substance has changed into a state where you are able to change it back such as:
Water melting
Water freezing
They are different by a phase shift of pi/2
It's absolutely TRUE...........
