Peroxide, which commonly is used to mean hydrogen peroxide is a liquid. Most other peroxides are either liquids or solids.
Elemental oxygen (O2) is a gas but it is not considered a peroxide.
Mixing iron nitrate and hydrogen peroxide produces oxygen gas. The reaction between iron nitrate and hydrogen peroxide results in the decomposition of hydrogen peroxide to produce oxygen gas as one of the products of the reaction.
There is no such thing as peroxide gas.... peroxide isn't a chemical, it is a part of a chemical. You can have hydrogen peroxide or sodium peroxide for instance, or other types of peroxides, but not just peroxide. But generally peroxides are strong oxidizing agents and are not healthy to ingest.
No, hydrogen peroxide is not an odorless gas. It is a colorless liquid with a slightly sharp odor.
Oxygen
Hydrogen peroxide decomposes to hydrogen and oxygen in the gas phase.
Oxygen gas is produced when manganese dioxide and hydrogen peroxide are mixed. This reaction occurs as the manganese dioxide acts as a catalyst to decompose the hydrogen peroxide into water and oxygen gas.
Yeast and hydrogen peroxide produce oxygen gas as a byproduct of their reaction. The yeast acts as a catalyst to break down the hydrogen peroxide into water and oxygen.
The peroxide, H2O2 =>(Mn as a catalysist)=> H2O + O2
The chemical formula of nitrogen peroxide is NO2. It is a reddish-brown gas with a sharp, pungent odor.
When peroxide comes into contact with organic material like food particles or bacteria in your sink, it breaks down and releases oxygen gas. This gas forms bubbles, causing the peroxide to bubble in your sink.
Oxygen gas is produced when hydrogen peroxide is mixed with potassium iodide. This reaction results in the decomposition of hydrogen peroxide to water and oxygen gas as well as the formation of iodine.
When hydrogen peroxide decomposes, it forms water and oxygen gas as products.
