Yes, this oxide has the chemical formula FeO.
There's no real answer to that. Rust is a non-stoichiometric compound, which is a fancy way of saying that it doesn't have a fixed or simple formula. In addition, it's largely ionic so it doesn't have molecules anyway. Iron(III) oxide, which is rather like dry rust, is a giant ionic lattice containing Fe3+ and O2- ions.

The scientific name is Iron Pyrite. Crushed Iron Pyrite is Greenish Brown and Real gold crushed is gold colored. Iron pyrite, a mineral composed of iron sulfide, FeS, is called fool's gold because it has the appearance (but no other properties) of gold.
It is called nitrous oxide which is normally called "laughing gas"
It's not a real compound

No, pure , real metals always form exclusively POSitive ions, binding in ionic compounds to non-metals (oxides, chlorides etc).
Oxygen oxide is not a real substance.
Many metals come in the form of ores, which are either a compound, or nuggets of pure metal embedded in rock. Iron Ore is real, and commonly known as haematite, Iron Oxide in rock. Gold Ore is real, the gold is usually pure as it reacts only under extreme circumstances, but it can sometimes be alloyed with other metals such as silver. Diamond Ore and Emerald Ore aren't technically accurate name, pure diamonds and emeralds are just found in rocks, the game calls blocks of this 'ores'.
Epinephrine C9H13NO3 (the officialname) is an organic compound and like all organic compounds is a primarily covalent (molecular) compound.The real giveaway is that ionic compounds (a metal cation with polyatomic anions) have high melting points and do not burn or char.
No, pyrite, or fools' gold, is a compound called iron disulfide (FeS2).
There is no such thing as a molecular compound. Hydrogen chloride, is a COVALENT compound, since it is a molecule made of 2 non-metals: Hydrogen and Chlorine. When Hydrogen chloride is in solution, it is called Hydrochloric acid. This time, there are separate ions of H+ and Cl- , but there are no real bonds between these two ions.
O.O! That isn't even a REAL word!
Iron Sulfide is FeS, meaning that this compound has one iron atom and one sulfur atom. Iron Sulfide is also known as pyrite, or fools gold. The gold color is completely natural, but it is much, much, less heavy than real gold. Another way to find out whether it is real gold or not is to bang it with a hammer. If it shatters instead of bending, it is fool's gold.
Yes it is real
If you mean MoO4 the oxidation number of Mo is 8 and the compound would be called Mo(VIII) oxide. This compound does not exist, it is theoretical- teachers and examiners often use such nonexistent compounds as teaching aids- why I don't know- i think it is misleading as there are plenty of real compounds about.
