The oxide Fe2O3 has: 70 % iron and 30 % oxygen.
yes
physical mixture
Since iron oxide is made from TWO elements (Fe, and O), it is a compounds and so you have a MOLECULE, not an atom of iron oxide.
Iron oxides are inorganiccompounds.
No. By definition iron oxide is a compound of iron and oxygen.
A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.
2
a. 1 iron atom per molecule. in total, two atoms
Yes
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
Yes. Iron II oxide does not contain carbon, only iron and oxygen. Therefore it is inorganic.
