Answer and Explanation: The chemical formula FeS stands for the compound iron(II) sulfide or ferrous sulfide. Fe is the symbol for iron (a transition metal), and S is the symbol for sulfur (a nonmetal).

Is FeS a compound or mixture?

Is FeS an ionic bond?
Explanation: The first thing to recognize here is that you’re dealing with an ionic compound made up of iron, Fe , a metal, and sulfur, S , a nonmetal.
How is FeS formed?
The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat) Page 2 Maine Geological Survey | 2 One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million atoms of sulfur) react with heat to make one molecule of iron sulfide (or a million molecules of iron sulfide).
What is true about FeS?
Expert-verified answer Option 3 is true about iron sulphide. Iron sulphide is not soluble in carbon disulphide. Iron sulphide is black brown in colour. Iron with sulphur combine to give iron sulphide.
Is FeS soluble in water?
The compound FeS is insoluble. We use the solubility rules to qualitatively classify whether a substance is soluble or insoluble in water. According to the solubility rules, sulfide salts of transition metals are insoluble.
What is ferrous sulfide used for?
As a pigment in ceramics, hair dyes, and glass containers [1, 7]. Treating exhaust gases and lessening heavy metal pollution. To synthesize hydrogen sulfide in the laboratory.
What is the name of the ionic compound FeS?
Iron(II) sulfide.
How do you name the compound FeS?
Is FeS a mineral?
Minerals. By increasing order of stability: Iron(II) sulfide, FeS. Greigite, Fe3S4 (cubic)
Is FeS yellow in colour?
The correct option is (c). Iron filings and sulphur after heating form iron sulphide, FeS which is black in colour.
Where is iron sulfide scale often found?
Iron sulfide is much more easily oil-wet than other mineral scales, so it is often found at the oil-water interface where it stabilizes emulsions and interferes with the separation process.
Is FeS a precipitate?
The FeS precipitation can be described as a pseudofirst-order diffusion-controlled process. The mass-transfer coefficient increased with temperature and pH, and decreased with ionic strength. Experiment results indicated that pH is the most influential factor on FeS formation.
What type of chemical reaction is the given equation FeS FeS?
The above reaction is a redox reaction in which there are only two atoms of elements are present. In this reaction, is a reducing agent while is an oxidizing agent.
Is iron sulfide poisonous?
Slightly toxic by ingestion. Will react with acids to produce toxic hydrogen sulfide gas. Target organs: None known. This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200).
Will FeS attract magnet?
Iron sulphide is not attracted towards magnet whereas its element (iron) is attracted towards magnet. This suggests that properties of compound are different to the properties of its constituents. In words, magnetic iron on chemical combination with sulphur, gives non magnetic iron sulphide.
Is FeS soluble or insoluble?
Most sulfides of transition metals are highly insoluble. Thus, CdS, FeS, ZnS, Ag2S are all insoluble. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.
Is iron sulphide magnetic?
Iron(II,III) sulfide is a blue-black (sometimes pinkish) chemical compound of iron and sulfur with formula Fe3S4 or FeS·Fe2S3, which is much similar to iron(II,III) oxide. It occurs naturally as the sulfide mineral greigite and is magnetic.
Is iron sulfide flammable?
The iron sulfide is a pyrophoric material, thus it can ignite spontaneously in contact with air.
What causes iron sulfide?
Pyrophoric iron sulfide is formed by the action of corrosive sulfur compounds on iron and steel in process facilities, particularly in vessels, storage tanks, and pipeline scraper traps.
Is iron sulphide a metal?
Iron and sulfur are both elements from the periodic table of elements. As such, each one has its own unique set of physical and chemical properties. Iron is a metal, while sulfur is a nonmetal. When these two are heated together, the iron atoms combine with the sulfur atoms to make a compound known as iron sulphide.
Is FeS covalent?
Therefore there will be a significant degree of covalent character in the Fe-S bonds due to the polarising effect of the cation on the anion. This is confirmed by experimental results and theoretical calculations which suggest that the charge on Fe is about +2/3 and the charge on S is about -1/3.
What is Fe charge?
In Iron (II) oxide, or Ferrous Oxide, or FeO, the Iron element (Fe) is bonded to the Oxygen, in the oxidation state of “2”. This means that the Iron has accepted 2 electrons from the Oxygen. Because of this electromagnetic interaction, the charge of the Iron (Fe) in FeO is 2+.
Is sulfur a metal?
The non-metallic chemical element sulfur, 3216S , referred to in Genesis as brimstone and identified as element by Lavoisier, is the tenth most abundant element in the universe and the fifth most common element on Earth.
How do you neutralize iron sulfide?
Dissolve sulfide deposits using a high pH chelating solution. Add an oxidizing chemical to oxidize the iron sulfide. Oxidizing chemicals include sodium hypochlorite, hydrogen peroxide, and potassium permanganate.
