Iron powder as with most other metal powders is flammable. Try lighting a piece of steel wool to demonstrate this.
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.
You get iron sulphide.
yes it is hard though
Iron powder is attracted by a magnet, sulfur is dissolved in carbon disulfide, but be careful: it is explosive, toxic and stinks (rotten cauliflower)
Iron filings are very small pieces of iron that look like a light powder.
Iron powder is not soluble in water.
Iron is magnetic but copper isn't. So I guess iron powder is magnetic while copper powder isn't.:)
you get magnesium oxide + iron
get a magnet that attracts iron
no
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.

Do you mean iron powder mixed with sulphur powder? Fe(s) + S(s) ---> FeS (iron sulfide)
You get iron sulphide.
the color
I want the answer
