a mixture
No, iron filings and powdered sulfur are a heterogeneous mixture because they do not mix uniformly. You can see distinct particles of both substances when they are mixed together.
A mixture of common salt and powdered sulfur can be separated using water. Since salt is soluble in water while sulfur is not, adding water to the mixture allows the salt to dissolve. The undissolved sulfur can then be filtered out, leaving a solution of saltwater. Finally, the salt can be recovered by evaporating the water.
Solutions are a type of mixture, so it's not really an either/or thing. However, in order to be considered a solution, the mixture must be homogenous, and a mixture of sulfur and iron filings is decidedly not homogeneous on a microscopic level. So it's (just) a mixture, not the specific type of mixture called a solution.
Yes, a mixture of powdered sulfur and copper fillings is possible. Both substances can be physically mixed together without undergoing a chemical reaction, so they would be considered a heterogeneous mixture.
One way to separate sulfur from a mixture of carbon particles and powdered roll sulfur is by using a process called sublimation. Sulfur sublimes at a lower temperature than carbon, so when the mixture is heated, the sulfur will turn into a gas and can be collected separately from the carbon particles.
Reacting iron with sulfur an iron sulfide is formed, not a mixture.
When a mixture of powdered iron and sulfur is heated, iron sulfide is formed. Iron sulfide is a compound composed of iron and sulfur atoms that have reacted together through a chemical reaction.

Sulfur is an element.
No, it is a mixture, as they are not liquids.
A magnet can be used to separate iron fillings from powdered sulfur. Iron fillings are magnetic and will be attracted to the magnet, while sulfur is non-magnetic and will remain unaffected.
Sulphur is an element. It is neither compound nor mixture.
