What type of reaction is iron sulfide?

exothermic reaction
It shows the exothermic reaction of two elements, iron and sulfur, to form the compound, iron sulfide.

What happens when iron reacts with sulfur?

Iron and sulfur react together when they are heated to make a compound called iron sulfide.

Is iron sulfide a 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.

Which condition is required for the reaction of iron and sulphur?

The equation for this reaction is: Fe + S —> FeS The mixture of iron (Fe) and sulphur (S) must be heated to melt the sulphur and initiate the reaction. Once the reaction has started it generates its own heat (an exothermic reaction), and glows red hot.

What are the properties of FeS?

Iron(II) Sulfide Properties (Theoretical)

Compound Formula FeS
Melting Point 1194 °C (2181 °F)
Boiling Point N/A
Density 4.75- 4.84 g/cm3
Solubility in H2O Insoluble

What is the property associated with iron sulfide?

powdered iron sulfide is pyrophoric (ignites spontaneously in air).

Is heating a mixture of iron and sulfur a physical or chemical change?

chemical change
Give reason why separation of mixtures example iron from a mixture of iron and sulphur is a physical change but heating a mixture of iron and sulphur is considered a chemical change.

Why is mixing of iron and sulphur a physical change?

Physical change There is no change in the specific properties of the constituents. Example: The particles of iron can be separated from sulphur with the help of a magnet or by dissolving sulphur in carbon disulphide. No new substance is formed. Example: The mixture of iron and sulphur does not form any new substance.

Which reaction below is a physical change?

Pounding, pulling, cutting, dissolving, melting, or boiling do not produce a new substance with new properties, so they are all physical changes.

When iron is heated with sulphur iron sulphide is formed what is the reaction called?

Chemical Reactions and Equations When iron is heated with sulphur, iron sulphide is formed. (Fe + S→>FeS). What is this reaction called? This reaction is called Combination reaction.

What happens when iron sulphide is heated?

Iron sulphide is heated in air to form A, an oxide of sulphur. A is dissolved in water to give an acid. The basicity of this acid is…. Iron sulphide reacts with sulphureic acid.
