One substance similar to hydrogen peroxide is bleach, which is also a strong oxidizing agent commonly used for cleaning and disinfecting.

The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.
The iron in haemoglobin is reduced oxidised by the hydrogen peroxide which is an oxidising agent.
H2O2 is a covalent compound, as a pure sample of it cannot be split into other separate compounds by physical means. However, the bottle labeled "Hydrogen Peroxide" in your medicine cabinet is actually a mixture (it's about a 3% solution of hydrogen peroxide the compound in water).
The material most commonly called "hydrogen peroxide", especially by non-chemists, is a solution of the solute hydrogen peroxide in water as the solvent.
Water and hydrogen peroxide both consist of hydrogen and oxygen atoms, but they have different chemical structures. Hydrogen peroxide has an extra oxygen atom compared to water, making it a more reactive molecule. Additionally, hydrogen peroxide is a stronger oxidizing agent compared to water.

A substrate is a substance in which an enzyme reacts. The substrate for catalase would be hydrogen peroxide otherwise known as H2O2.
Hydrogen peroxide can decompose in the presence of certain substances, such as metals like iron or copper, as well as enzymes like catalase found in living organisms.
Absolutely anything. Peroxide is so unstable that anything that oxygen can nucleate on will catalyse the decomposition. That includes ions, dust, other gas bubbles, you name it, although the reaction rate will vary.
Hydrogen Peroxide (H2O2) is a compound, and liquid at room temperature. It is NOT a mixture. However, at room temeprature it slowly decomposes to oxygen and water. 2H2O2 = 2H2O + O2 It the oxygen remains in solution in water then it is heterogeneous solution, NOT Mixture.
Cells produce hydrogen peroxide as a byproduct of many metabolic processes, but it is toxic to cells if it accumulates. Cells have enzymes like catalase to break down hydrogen peroxide into water and oxygen, preventing cellular damage. If cells are unable to break down hydrogen peroxide, it can lead to oxidative stress and damage to cellular components.
