Yes, it is. Peroxide, or hydrogen peroxide, H2O2, is a powerful oxidizer. It oxidizes stuff, or causes stuff to combine with the oxygen. The reaction kills bacteria, because they are vulnerable to this destructive chemical. It also "kills" a bit of tissue that is exposed, but not too much. The "big loser" here is any bacterial agent that is exposed to this chemical. When the hydrogen peroxide is put on a wound, oxygen is liberated. That is the reason you see all the bubbles. The H2O2 is unstable, and is being applied as a solution of just a few percent, but the action is fierce. And a good one it is. This stuff is a fabulous "cleaner" of minor wounds, or even major ones. It is applied drop by drop or as a "dribble" to clean out the area of injury before an antiseptic solution or cream is applied or sutures are put on.

Why is water change to hydrogen peroxide a chemical change?

The transformation of water into hydrogen peroxide involves a rearrangement of atoms and the formation of new chemical bonds, resulting in a completely new substance with different properties. This chemical reaction cannot be reversed by physical means and is accompanied by the absorption or release of energy, which is characteristic of a chemical change.

Is hair being bleached with hydrogen peroxide a chemical property?

Hair being bleached with hydrogen peroxide is a chemical change, not a chemical property. Chemical properties describe how a substance reacts with other substances to form new substances, while a chemical change involves the actual rearrangement of atoms and molecules in a substance. In this case, hydrogen peroxide is breaking down the pigment molecules in the hair, causing it to change color.
