When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.

Details of the chemical reaction of oxygen with the [Fe-S] cluster reveal how this cofactor is used for oxygen sensing.

Watch this video to see a practical investigation into the reactivity of iron. Metals can react with water, acid and oxygen. The reactivity of the metal determines which reactions the metal ...

So what’s the secret? Rust is the result of iron reacting with oxygen in air or water to form iron oxide. The corrosive process, known as oxidation, weakens the underlying material. But ...

Iron present in exposed rocks reacts with this oxygen, and rust colors the planet ... on the ocean floor are the product of a chemical reaction: rust. The alternating layers of rust-colored ...

Bacteria living in these oxygen-limited environments replace oxygen with iron. And instead of the metabolic reactions occurring within cells, the bacteria actually move electrons into the external ...

Our immune systems rely on iron to function, but so do invading viruses and bacteria. New research from Binghamton University ...
