One. The II in Iron II means that the ion has a 2+ charge. Oxygen atoms, when they are not bonded to any other atoms (include another oxygen) have a 2- charge. So, when the 2+ and the 2- react, they form a very stable bond.
Here's the reaction.
Fe2+ + O2- --> FeO
Basically there are 2 forms of iron:iron 2+ and iron 3+ Iron 2 oxide, basically is Fe2+ in order to stabilize it you need 2- which is exactly one oxygen ion therefore we get FeO While iron 3 oxide is Fe3+ in order to make a stable compound we need 2 Fe 3+ along with 3 O 2- which gives us +6 and -6 therefore a stable compound which is Fe2O3 the hydrated form of iron 3 oxide is rust.
Iron + Oxygen ---> Iron III oxide
4Fe + 3O2 ---> 2Fe2O3
Type your answerA.contains 2 iron and 3 oxygen atoms.B.has an Fe3+ ion.
here...
Fe2o3
combination
Magnesium and oxygen combine to form magnesium oxide. It is basic in nature.

"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
Nitrous oxide, commonly known as laughing gas, is a chemical compound with the formula N2O, so it consists of TWO elements: Nitrogen (2 atoms) and Oxygen (1 atom), which are together three ATOMS.

From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.

Most of the non-metals combine with oxygen to form acidic oxides.
reactants: iron and oxygen products: rust (aka: iron (II) oxide or FeO)
Yes; for example, two oxygen atoms combine to form an oxygen molecule.
