with a magnet! powered iron will stick to the magnet laving the glass behind
Eddy current separator
it will get on the iron if you try to separate sand will be on the iron
Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
You need a magnet to separate iron from a mixture (not from a compound).
You can put the mixture in water where the wood will float and the the iron sink, or separate them with a magnet, where the iron will be attracted and the wood will not.
It has a greater surface area than the single piece of iron
Use a magnet.

Iron is a magnetic metal, aluminium is not.So, a simple method is to use a magnet for this separation.Magnetic separation is frequently used to extract iron from wastes.
You would run a magnet over both of them together and the iron would stick to the magnet but the aluminum would not stick to the magnet or other way around. love, Hannah age 12

Nothing!
A reaction occurs more quickly when powdered iron is used instead of a single piece of iron of the same mass because the powdered iron has a much greater surface area and all chemical reactions take place on surfaces.
No, the mixture of powdered sulfur and iron filling are not a homogenous mixture, they are a heterogenous mixture.
A magnet will attract the iron beads but not the glas beads
inks and dies are added to glass when it is in powdered form, then mixed in
If the mixture is powdered sulfur and iron filings, use a strong electrostatic field. The sulfur will jump to the opposite charge leaving the conductive iron behind. ***************************** Or, you could add carbon disulfide which would dissolve the sulfur.
iron sulfide, FeS or Fe3S2
