∙ 9y agoIron sulfide is brown crystals. Iron is a silvery metal. Sulfur is bright yellow crystals. Sulfur burns with a bright flame. Iron doesn't burn and iron sulfide doesn't burn well.
Mixture of metallic and non-metallic substances can be separated using magnet. For example - mixture of same and iron powder.
Solid iron oxide and a poisonous called sulphur dioxide
The iron and sulphur are heated to a certain temperature until they start to react with each other. The iron and sulphur bind together in the heating process and turn into one compound. That compound is IRON SULPHIDE. When the two are both chemically joined they turn red in colour and the process of turning the mixture in to the compound is complete.
Preparation of Iron Sulphide can be easily done by using heating process.Things You Need:Iron pieces(small)Sulphur PowderPetri dishesBurnerProcedure:First of all mix Iron and sulphur in a ratio of 7:4 by weight.Put them in a petri dish.Start heating the mixture.Soon the yellow sulphur will darken to black.The remaining black compound is iron sulphide.Precautions:Sulphur is highly flammable so be careful while heating.
Pyrite is made of iron and sulfur and is the compound iron sulfide with the chemical formula FeS2. It is not a mixture of iron and sulfur. The iron and sulfur are chemically combined to form a compound.
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
because a mixture is physically combine while a compound is chemically combine thus make is eaiser for the mixture to separate using the technique magnetic separation.
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
It is a compound because iron and sulfur are two individual elements that you can find on the periodic table.
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
It is a chemical reaction
It depends on the temperature. If you only heat moderately, you will still have a mixture of iron and sulfur, even if the sulfur has melted and formed a kind of cement with the iron. If you put the mixture in a vacuum, and then heat up to the combustion temperature of the mixture, then you would get some amount of iron sulfide, which is a compound. You need the vacuum so that the sulfur, for instance, does not react with oxygen and just burn down to sulfur dioxide gas, probably leaving the iron mostly unaffected. If you have the exact ratio of iron to sulfur for reaction, you will get only iron sulfide compound, but any other ratio will leave either some iron or some sulfur unreacted.
sulfur and iron are elements, sulfur a yellow powder and iron a metal. When mixed together at room temperature they do not react readily and constitute a mixture which can be separated say by using a magnet to attract the iron. Heat them up and a vigorous reaction ensues forming a chemical compound, black iron sulfide, Fe2S3 see link for experimental details
It's just physical, unless you heat the mixture. The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves. The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
