Its difficult to understand your question, I can make an assumption (although your stoichiometry is off).
Are you asking about Iron Oxide compounds?
Iron is a transition metal, abbreviated "Fe." It has two oxidative states, +2 and +3--often written as Fe (II) and Fe (III).
If you have Fe(II) oxide, FeO, it would be called "ferrous oxide."
If you have Fe(III) oxide, Fe2 O3, it would be called "ferric oxide."
The other forms in your question aren't correct and I cannot answer them.
What else can I help you with?
What is common name for FeO2?
Rust.
What is the mass in grams of 4.2 mols of Feo2?
To find the mass of FeO2 for 4.2 moles, you first need to calculate the molar mass of FeO2. Iron (Fe) has a molar mass of 55.85 g/mol, and oxygen (O) has a molar mass of 16.00 g/mol. Adding these together gives a molar mass of FeO2 of 87.85 g/mol. Therefore, the mass of 4.2 moles of FeO2 is 4.2 moles * 87.85 g/mol = 368.37 grams.
Is FeO2 an ionic compound?
No, FeO2 is not an ionic compound. It is more likely a covalent compound based on the elements it consists of (iron and oxygen). Iron can form both ionic and covalent compounds, but in the case of FeO2, it is more likely covalent due to the high oxidation state of oxygen.
Is FeO2 a liquid or solid?
FeO2 is a solid. It is a compound composed of iron (Fe) and oxygen (O) atoms, and it typically exists in a solid form at room temperature and pressure.
How many grams of FeO2 can be produced from 50.0 L of O2 at STP?
To calculate the mass of FeO2 produced, we first need to find the number of moles of O2 using the ideal gas law: PV = nRT. At STP, 1 mole of gas occupies 22.4 L, so 50.0 L of O2 is 50.0/22.4 = 2.23 moles. The balanced equation for the reaction will tell you the stoichiometry needed to calculate the mass of FeO2 produced.
What is the empirical formula of an iron oxide that 65.0 percent fe and 35.0 percent O?
The empirical formula of the iron oxide compound is Fe₂O₃. This is determined by dividing the percentage of each element by its molar mass to find the ratio of atoms in the compound.
What is common name for FeO2?
Rust.
Is feo2 organic?
inorganic
Is this the way the chemical equation for Iron oxide written FeO2?
fe + 2 O ------> FeO2 iron II oxide
What is the ticker symbol for iron oxide?
FEO2

What are the classifications of Iron?
FeO2= is a ferric ion where FeO3- is a ferrous ion.
Is rusting a nail a physical change or chemical change?
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3

What is the color of iron oxide in water?
Kind of reddish brown. FeO2 is commonly called rust.
