If iron is put in water and oxygen is present the following will happen. 4 Fe + 3 O2 + 6 H2O -> 4 Fe(OH)3 Basically the Iron corrodes/rusts. The same thing will happen in moist air. This is why when paint is scratched off a car the metal eventually rusts
The iron filings sink because the powder is dense The sulphur powder floats
A black compound iron sulphide (FeS) is formed. The reaction is quite strongly exothermic, which means it gives out heat.
physical change
Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
As the mixture of iron filings and sulphur powder are together/mixed it can be easily separated by a magnet.
A compound, iron sulfide, is formed by chemical reaction between the iron and the sulphur. Depending on reaction conditions, either iron (II) or iron (III) sulphide or a mixture of both of them will be formed.

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.
When sufficiently heated, iron filings and sulfur react to produce a compound, iron (II) sulfide.
Mixture!:)
Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
As the mixture of iron filings and sulphur powder are together/mixed it can be easily separated by a magnet.
Use a magnet to lift out the iron filings.
The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
Nothing Top Donny GG
if you dont know this your an idiot
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
A "mixture" is a group of several chemicals that have been mixed together in such a way they can be easily separated, usually without altering the state of matter of any of the chemicals. Iron filings and sulfur powder would be a mixture; you can separate the two with just a magnet. Similarly, sand and sulfur powder would be a mixture. Just put it in water; the sulfur will float and the sand will sink.
Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
