Why the mixture of the metal fillings and sulfur becomes chemical change when heat was applied?
Applying heat to the mixture causes a chemical reaction to occur: 2Fe + 3S -> Fe2S3
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.
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.
How does sulfur react with heat?
sulfur reacts violently with heat causing flames
Chemical Product of CuCO3 with change of heat?
CuSO3 + heat = CuO + SO2 so Copper oxide and sulfur dioxide are produced.

How is sulfur mined?
Sulfur is extracted by two main processes: Sicilian and Frasch. Sicilian- powdered sulfur is put on the top of the deposit and ignited. AS it burns the sulfur melts from the heat causing the molten sulfur to flow down the hills. Cool huh? Frasch- uses pipes to heat the sulfur, air compresses it (to foam) and it flows out the pipe.
Is heating up sulfur a chemical change?
It is not a chemical change, unless you heat it sufficiently to make it catch fire.

How can you separate carbon and sulfur?
The simplest way is to heat the mixture in toluene or xylene (check the hazards first and take appropriate precautions) in a safety bath. The sulfur will dissolve and the carbon won't. You can filter out the carbon and crystallize the sulfur.
Why is heating of sulphur considered as a physical change?
Simply heating (warming) sulfur could be a physical change if nothing happens to the sulfur other than it just getting warmer, and when you remove the heat, it stays as the original sulfur. However, more likely than not, heating sulfur will cause a CHEMICAL change where the sulfur combusts and turns into sulfur dioxide (SO2).

How can you separate a mixture of sulferplus sand plus sugar plus ironfillings?
Magnets would remove the iron. sugar is water soluble now you have sulfur and sand mixed. Apply heat sulfur will burn before the sand.
Why is it impossible to separate iron filings from sulphur after heating?
The application of heat caused the iron atoms and the sulfur atoms to merge into molecules of iron sulfide. In other words, heat changed the mixture to a compound.
