Why doesn't hydrogen peroxide fizz when i put it in my ear?
The chemical formula for hydrogen peroxide is H2O2. When it decomposes, it separates into water and oxygen gas. The reaction takes this form: 2 H2O2 -------> 2H2O + O2 The release of the oxygen gas is what makes the fizzy bubbles. When you put hydrogen peroxide solution on a wound or in your ears, it saturates the area with oxygen. Bacteria cannot live in this environment, and this is what makes peroxide a good disinfectant. It doesn't really help too much with earwax, though.
Can you purify your water well with hydrogen peroxide?
No, hydrogen peroxide is H2O2, meaning in each molecule there are two hydrogen atoms and two oxygen atoms. Water is H2O, meaning that each molecules has two hydrogen atoms and one oxygen atom. Hydrogen peroxide has different chemical and physical properties from water. It is more acidic, more viscous, and has a higher boiling point. It decomposes easily into water and oxygen and is a strong oxidizer.
Why are catalysts important in chemical reaction?
Catalysts are important in chemical reactions because they change the rate of a chemical reaction. However, catalysts themselves are not actually a reactant of a reaction. For example, magnesium oxide is a catalyst to hydrogen peroxide, which speeds up the rate that hydrogen peroxide decomposes.
How does Hydrogen peroxide decomposes much faster in the presence of enzyme catalysts?
Try a peroxidase enzyme. For example "Versatile peroxidase", Jena Biosciences #EN-203L is an extremely effective catalyst.
What is the element for h202?
H2O2 is the formula for hydrogen peroxide.
Is hydrogen peroxide a disinfectant?
yes it is mild disinfectant.
What does Hydrogen peroxide decompose into?
Hydrogen peroxide decomposes into water and oxygen.
What does hydrogen peroxide do to cuts?
Hydrogen peroxide is a disinfectant. It kills bacteria that might cause and infection.
What is hydrogen peroxide broken down into?
Hydrogen peroxide spontaneously decomposes into water and oxygen.
What happens when hydrogen peroxide decomposes?
h2o2 decomposes to o2 and h2o.h2o2 is very harmful
Hydrogen peroxide decomposes to hydrogen and oxygen in what states of matter?
liquid or gas
Mix hydrogen peroxide and liver?
The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules.
Which of the following chemicals is a disinfectant for soft contact lenses?
hydrogen peroxide
What are the uses for hydrogen peroxide?
It is most commonly used as a disinfectant and as a bleach.
What is hydrogenated water How does it differ from hydrogen peroxide and water solution?
hydrogenated water is hydrogen rich water.hydrogen peroxide act as a disinfectant for water.
What is the formula when liquid hydrogen peroxide decomposes to liquid water and oxygen gas?
hydrogen peroxide is H2O2 break down occurs 2H2O2 - 2H2O + O2
Liver plus hydrogen peroxide equals what and what?
When Hydrogen Peroxide (2H2O2) is combined with a small piece of liver, the hydrogen peroxide decomposes. This is because the small piece of liver acts as a catalyst, or the cause, of the decomposition of the Hydrogen Peroxide.The balanced equation is thus:2H2O2 (Hydrogen Peroxide) ---------> 2H2O + O2
