Rust.
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.
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.
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.
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.
Iron (Fe) and Oxygen (O). The subscript "2" indicates that there are two oxygen atoms in the compound.

The abbreviation for Iron is Fe on the periodic table[which is the abbreviation of the latin "ferrous"] . The abbreviation for Oxygen is O on the periodic table. When the two are mixed, FeO2 is created, known as ferrous oxide. It's common name is rust.
FeO2= is a ferric ion where FeO3- is a ferrous ion.

The common name is horsetails.
