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.
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.
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.
Is iron sulphur a compound?
Iron sulphur is not a compound, but a mixture of iron and sulfur elements. Compounds are substances composed of two or more different elements chemically combined in fixed ratios, whereas mixtures are combinations of different substances that are not chemically bonded.
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.
Is iron filings and sulfur a element a mixture or a compound?
Iron filings and sulfur together form a mixture, not a compound. A compound is a substance formed by the chemical combination of two or more elements in a fixed ratio, while a mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.
Is iron filings and powdered sulfur a homogeneous mixture?
No, iron filings and powdered sulfur are a heterogeneous mixture because they do not mix uniformly. You can see distinct particles of both substances when they are mixed together.
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.
Why is it easier to separate a mixture of iron and sulfur than to separate a compound of iron and sulfur?
It is easier to separate a mixture of iron and sulfur because the two substances retain their individual properties and can be physically separated by techniques like magnetism or filtration. In a compound of iron and sulfur, the atoms are chemically bonded, forming a new substance with different properties, making separation more challenging as it requires breaking chemical bonds through a chemical reaction.
What is mixing sulfur with iron fillings?
When you mix Iron filings and Sulphur crystals together, you form a mixture of Iron and Sulphur from which both the components can be separated by physical means. But if you heat the mixture strongly, then it becomes a compound of Iron Sulphide from which the two components cannot be separated by physical means.
What is formed when a mixture of powdered iron and sulfur is heated?
When a mixture of powdered iron and sulfur is heated, iron sulfide is formed. Iron sulfide is a compound composed of iron and sulfur atoms that have reacted together through a chemical reaction.
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.
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.
