Copper (Cu) and iron (Fe) in their solid forms (Cu(s) and Fe(s)) are considered elements, as they consist of only one type of atom each. When combined, they do not form a compound unless they undergo a chemical reaction to create a new substance. Therefore, Cu(s) plus Fe(s) remains a mixture of elements rather than a compound.

FES is referred to as a compound because it is a chemical substance composed of two or more elements in a fixed ratio. In the case of FES, it is composed of iron (Fe) and sulfur (S) atoms in a specific stoichiometric ratio, which gives it the chemical properties unique to the compound.
The balanced chemical equation for this reaction is: FeS + 2H⁺ → Fe²⁺ + H₂S
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
Iron sulfide is a compound because it is composed of two or more different elements, in this case iron and sulfur, which are chemically bonded together in a fixed ratio. Its chemical formula, FeS, indicates that it is a compound.

fecl3 is a compound called iron chloride. i2 is an element called iodine. fes is a compound called iron sulphide. s and k are elements sulpher and potassium
FES is referred to as a compound because it is a chemical substance composed of two or more elements in a fixed ratio. In the case of FES, it is composed of iron (Fe) and sulfur (S) atoms in a specific stoichiometric ratio, which gives it the chemical properties unique to the compound.
The empirical formula of the compound containing 53.73% Fe and 46.27% S is FeS. This is determined by dividing the given percentages by the molar mass of each element to find the mole ratio, which simplifies to FeS in this case.
When iron reacts with sulfur, it forms iron sulfide. This is a chemical compound with the formula FeS. It is a grayish-black solid at room temperature.
There are two atoms in the compound FeS: Sulfur and iron.
Iron (II) sulfide
The balanced chemical equation for this reaction is: FeS + 2H⁺ → Fe²⁺ + H₂S
Sulfide is a compound composed of sulfur and a metal. It is not a metal by itself, but a type of mineral formed by the combination of sulfur with a metallic element, such as iron sulfide (FeS) or copper sulfide (Cu2S).
There is only one product, the ionic compound iron(II) sulfide.iron + sulfur --> iron(II) sulfide Fe + S --> FeS
The balanced equation for FeS + O2 → SO2 + FeO is: 4FeS + 7O2 → 2SO2 + 2FeO
