Catalase breaks down hydrogen peroxide into water and oxygen. Catalase is found in blood and bacteria in the wound. The bubbles you see are from the oxygen that is being released.

Is hydrogen burns in chlorine gas chemical or physical change?

When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat


When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?

This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.


If making ammonia from nitrogen and hydrogen A chemical or physical change?

Making ammonia from nitrogen and hydrogen is a chemical change because it involves a rearrangement of the atoms in the reactants to form new chemical compounds in the product (ammonia). This process is characterized by the breaking and forming of chemical bonds.


Is peroxide on a sore a chemical change?

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.


What is the reaction of hydrogen peroxide with 4-aminoantipyrine and phenol?

The reaction of hydrogen peroxide with 4-aminoantipyrine and phenol forms a colored complex that is often used in the detection of hydrogen peroxide. The combination of these compounds typically results in a color change to a pink or red hue. This reaction is commonly utilized in analytical chemistry for the determination of hydrogen peroxide levels.

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 hydrogen peroxide cleaning a cut a physical or chemical change?

When hydrogen peroxide is applied to a cut, it often undergoes a chemical change as it reacts with enzymes in the damaged tissues to release oxygen gas. This bubbling action helps clean the wound by removing debris and bacteria.

Yes it is.


Is a cut healing a physical or chemical change?

Chemical. The hydrogen peroxide breaks down into water and elemental oxygen. Two new substances are created.


When hydrogen peroxide is poured on a cut on a persons skin the hydrogen peroxide breaks down into water and oxygen gas what type of change is this?

This is a chemical reaction. A decomposition reaction.


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.
