Iron (III) oxide, Fe2O3, is rust, which is a solid.
Fe and Cl are chemical elements situated in the periodic table.FeCl2 is a chemical compound.
Fe + 2x Cl = Fe + Cl + Cl = 3 atoms per molecule.
The chemical equation is:4 Fe + 3 O2 = 2 Fe2O3
The metals, except for mercury, which is liquid at room temperature.

Fe2+Cl=FeCl (Original)Fe2+2Cl=2FeCl (Balanced)---- The two in front of the FeCl balances Fe by making it Fe2, but also turns Cl into Cl2. So you put a 2 in front of the Cl reactant, balancing Cl and Fe.
The correct symbol for chlorine is Cl, and for iron is Fe.
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.
Visually you would see an effervescence in the acid where a gas appears to be being released from the metal coin. This is actually Hydrogen gas being released as part of the chemical reaction for example Iron (FE) mixed with dilute Hydrocloric acid (H2O & H-CL) would produce FE-CL and H2 and H2O
An ionic bond will form between iron (Fe) and chlorine (Cl) since iron tends to lose electrons to become positively charged (Fe^3+) and chlorine tends to gain electrons to become negatively charged (Cl^-). This opposite charge attraction results in the formation of an ionic bond between Fe and Cl.
It's BROMINE. That is the element that is a liquid in the same period as Fe.
The oxidation state of Fe in FeCl3 is +3. Each Cl atom has an oxidation state of -1, and since there are three Cl atoms in FeCl3, the overall charge from the Cl atoms is -3. This makes the Fe atom's oxidation state +3 to balance the charges.
C and N, N and H, Cl and Cl, Xe and Xe can form covalent bonds. Mg and Cl, Li and Cl, Cu and Cl, Fe and Cl can form ionic bonds due to the large difference in electronegativity. K and Cl would form an ionic bond as well.
Molten iron is the same element as solid iron, so the chemical symbol is Fe. Iron is not soluble in water, so you won;t find Fe(aq)
1. Iron and iron oxides are solids. 2. Carbon oxides are gases.
FeCl2 is an ionic compound. It is composed of iron (Fe) cation and chloride (Cl) anion, which are held together by ionic bonds formed through the transfer of electrons from Fe to Cl.
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and chlorine (Cl)
