Give one way that iron sulphide is different from a mixture?
Iron 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.
What mixture can be separated using a magnet?
Mixture of metallic and non-metallic substances can be separated using magnet. For example - mixture of same and iron powder.
What two products are formed when iron sulphide is heated in air?
Solid iron oxide and a poisonous called sulphur dioxide
What is the reaction of iron and sulphur?
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.
How colud you conduct a practical to make iron sulfide?
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.
What mineral is made by sulfur and iron and is also a mixture?
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.
How is iron sulphide a compound and not just a mixture of iron and sulfur?
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.
Describe why iron filings and sulfur can be classified as element compound or 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.
Why is it easier to separate a mixture of iron and sulfur than to separate a compound of iron and sulfur?
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.
How did the properties of the sulfur alone compared with the sulfur in the unheated iron sulfur combination?
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.
How do you know iron sulphide is not a 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.
Is iron sulphide a compound mixture or element?
It is a compound because iron and sulfur are two individual elements that you can find on the periodic table.
Why can iron sulphide be classified as an element compound or a 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.
When a mixture of iron and sulfur are heateda compound called iron sulphide is producedwhat type of change is this?
It is a chemical reaction
When a mixture of iron and sulfur are heated how would you classify the resulting material?
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.
Is sulfur and iron an element or a compound or a mixture?
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
Is mixing iron filing and sulfur is a physical change?
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.
