Is iron sulfide a chemical or physical change?
The authors say: Mixing iron and sulfur is not a chemical change but a physical change since a new substance is not formed.
What happens when iron sulfide is heated?
When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and form ferrous sulphide (FeS). It is a new substance which has properties entirely different from Fe and S. Therefore, heating of a mixture of iron and sulphur powder is a chemical change.
What is the chemical reaction of ferrous sulfide?
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).

Why is mixing iron and sulphur a physical change?
Physical change: The properties of iron and sulphur do not change when they are separated. There is no formation of a new product in this change. There is no change in the heat energy level of the mixture. The change is temporary and reversible as iron and sulphur can be mixed again.
Did the compound iron sulfide have similar properties?
Iron and sulfur react together when they are heated to make a compound called iron sulfide. the iron and sulfur still behave like iron and sulfur in the mixture, but iron sulfide has different properties from both iron and sulfur.
What are physical and chemical properties of iron?
Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.

What is the difference between chemical change and physical change?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. All chemical reactions are reversible although this can be difficult in practice.
How does spontaneous combustion of iron sulfides produce carbon dioxide?
At the elevated temperatures induced via the spontaneous combustion of iron sulfides, various carbon phases can ignite and burn in the presence of oxygen. This process can generate what is regarded as a more conventional fire; the production of carbon dioxide and carbon monoxide from the oxidation of carbon.
What is the physical and chemical properties of iron sulfide?
Physical and chemical properties of iron sulfide (II) Iron (II) sulfide is a dark brown or black metal-looking solid. When it is pure it is colorless (National Center for Biotechnology Information, S.F.). Figure 2 shows the appearance of ferrous sulfide. Figure 2: Iron sulfide (II) appearance.
What causes the iron sulfide film in internal carbon steel?
The iron sulfide film in internal carbon steel is mainly caused by corrosive media (H 2 S /CO 2 and Cl – in liquid water). It could start an intense exothermic reaction only when the corrosion is exposed in air. Self-heating, and even spontaneous combustion, has imposed a serious problem in oil and gas fields.
Can iron sulfide spontaneously ignite?
Iron sulfide, a dark brown or black mass with metallic luster, can spontaneously ignite when exposed to oxygen in the air. It is easier to ignite when exposed to air.
