It's just physical, unless you heat the mixture.
The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves.
The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
What else can I help you with?
Is grinding sulfur a chemical or physical change?
Grinding sulfur is a physical change because the substance is still sulfur; only the form has changed from solid pieces to smaller particles. No new substances are formed during grinding.
Is melting sulfur a physical change?
Yes. Any state changing is physical, unless it's a chrystal.
Is a lump of roll sulphur being crushed a physical or chemical change?
Crushing a lump of roll sulfur is a physical change, as the chemical composition of the sulfur remains the same. The process only alters the physical state of the sulfur without changing its chemical properties.
Is a lump of sulfur being crushed physical or chemical?
Crushing a lump of sulfur would be considered a physical change because the chemical composition of sulfur remains the same before and after crushing. No new substances are formed during the process.
Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Is the mixing of iron and sulfur a physical change or chemical change?
It is always categorized as a Physical change as no new substance with different properties forms.
Have iron and sulfur undergone change in properties after mixing?
No. Making mixtures are physical changes and the chemical substances will not change.
Is burning of sulfur physical change?
Burning of sulfur (or anything else) is a chemical change, not a physical change.
Is grinding sulfur a chemical or physical change?
Grinding sulfur is a physical change because the substance is still sulfur; only the form has changed from solid pieces to smaller particles. No new substances are formed during grinding.
Is melting sulfur a physical change?
Yes. Any state changing is physical, unless it's a chrystal.

This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Is converting sulfur to sulfuric acid a physical change?
No, this is a chemical change.
Is burning sulfur physical or chemical change?
chemichal
Is dissolution of sulfur in carbon disulphide is chemical or physical change?
The dissolution of sulfur in carbon disulfide is a physical change because no new substances are formed. The sulfur particles are still sulfur particles, they are just dispersed within the carbon disulfide, similar to dissolving sugar in water.
Why is heating of sulphur considered as a physical change?
Simply heating (warming) sulfur could be a physical change if nothing happens to the sulfur other than it just getting warmer, and when you remove the heat, it stays as the original sulfur. However, more likely than not, heating sulfur will cause a CHEMICAL change where the sulfur combusts and turns into sulfur dioxide (SO2).
