do you mean pheomelanin the pigment in hair and skin?
Pheomelanin is also found in hair and skin and is both in lighter skinned humans and darker skinned humans. Pheomelanin imparts a pink to red hue and, thus, is found in particularly large quantities in red hair. Pheomelanin is particularly concentrated in the lips, areola, nipples, glans of the penis, and vagina. Pheomelanin also may become carcinogenic when exposed to the ultraviolet rays of the sun. Chemically, pheomelanin differs from eumelanin in that its oligomer structure incorporates benzothiazine units which are produced instead of DHI and DHICA when the amino acid L-cysteine is present.
No, iron oxide is not a gas. It is a solid compound composed of iron and oxygen atoms.
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
The word equation for calcium plus iron oxide is: calcium + iron oxide → calcium oxide + iron. In this reaction, calcium displaces iron in iron oxide to form calcium oxide and elemental iron. This type of reaction is known as a displacement reaction, where a more reactive element displaces a less reactive element in a compound.
Iron oxide contains iron as the metal component.
because they contain large amount of iron oxides
No. By definition iron oxide is a compound of iron and oxygen.
Yes
Yes. Iron II oxide does not contain carbon, only iron and oxygen. Therefore it is inorganic.
The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
That compound is Iron Oxide. It contains iron and oxygens.
Yes. Iron II oxide does not contain carbon, only iron and oxygen. Therefore it is inorganic.
Cerium oxide is non ferrous, as it does not contain any iron.
Iron oxide is not considered an organic molecule because it does not contain carbon-hydrogen bonds. Organic molecules are generally compounds that contain carbon atoms bonded to hydrogen atoms. Iron oxide is an inorganic compound composed of iron and oxygen atoms.

Yes, at least in minute quantity.
