How many iron(ii) ions combine with oxygen to form iron(ii) oxide?

It depends which iron oxide you mean. Iron(II) Oxide, FeO, which is black and has 1 oxygen molecule bonded with an iron one . Iron(III) Oxide (Fe2O3) ie rust has 2 iron molecules bonded to 3 oxygen molecules.


If eight atoms of iron react completely with six molecules of oxygen how many units of iron oxide will be formed?

If 8 atoms of iron react with 6 molecules of oxygen, they will form 4 units of iron oxide (Fe2O3) because each molecule of iron oxide contains 2 atoms of iron and 3 atoms of oxygen.

What compound is formed when iron is burned?

When iron is burnt (heated) and exposed to air the iron will combine rapidly with oxygen atoms to form FeO molecules (FeO - Iron Oxide - Also known as 'rust' on iron materials)


Oxygen in the air combines with iron molecules on a frying pan to form?

iron oxide, commonly known as rust. This process is called oxidation, where the iron molecules react with oxygen to create a reddish-brown layer on the surface of the frying pan.


How does oxides affect airon mass?

Oxides, like rust (iron oxide), can increase the mass of iron due to the addition of oxygen atoms from the oxide molecules. This increase in mass occurs because of the combination of iron with the oxygen in the oxide.


How many elements in iron oxide?

Iron oxide has two main chemical compounds: iron(II) oxide (FeO) and iron(III) oxide (Fe2O3). Both compounds consist of two elements - iron and oxygen.


Is iron oxide a organic molecule?

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.
