Heating a mixture of sulfur powder and iron fillings will produce Generation of black iron sulfide (FeS) because of insufficient oxidation of sulfur into the iron oxide +3, and Fe2O3 iron sulfide is black, not yellow over iron sulfide (FeS2) ,can be called pyrite.
Use iron fillings and sulphur powder and distinguish
between these on the basis of:
i) appearance i.e., homogeneity and heterogeneity
ii) behavior towards a magnet
iii) behavior towards carbon disulphide a solvent
iv) effect of heat.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
When temerature is high enough: Fe + S --> FeS (+ heat, energy)
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
Many people confuse gunpowder and black powder. Both of them are mixtures, although gunpowder, also known as smokeless powder, was 100% nitrocellulose, a compound, when it was first used in the mid 1800's. Black powder is a very intimate mixture of potassium nitrate, sulfur and charcoal. Smokeless powders today get their energy when burned from 100% nitrocellulose to mostly nitroglycerine. Most smokeless powders obtain their energy from a mixture of nitrocellulose and nitroglycerine. However, even smokeless powders made today with pure nitrocellulose are still a mixture because manufacturers add other compounds to the powder to reduce the muzzle flash, stabilize the burning rate, slow the decomposition of the powder and to neutralize any corrosive acids formed from the powder's decomposition.
Answerit is actually a mix of a couple compounds.
That produces a strongly exothermic reaction that results in the production of a grey substance, an iron sulphide. Please see the link.

H2 (g) + FeSO4 (s) hydrogen gas and iron sulphate
When temerature is high enough: Fe + S --> FeS (+ heat, energy)
Use a magnet to lift out the iron filings.
get a magnet that attracts iron
because it may cause irritation to your eyes
five examples of mixture are 1.sulphur powder and iron fillings 2.rice and pulse 3.nuts and bolts 4.salt and water 5.sandwich
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
Copper sulfides, but only after heating the mixture.
The vinegar dissolves the powder and its particles sink to the bottom of the mixture, leaving a cloudy look.
you use a magent
