I have no clue what the answer is. That's why I came on here; to find the answer! UGH!
Iron sulfide (FeS2) physical properties:
- density: cca. 4,9 g/cm3
- Mohs hardness: 6-6,5
- paramagnetic
- insoluble in water
they are both elements
Neither. Sulfur is an element by it self , that has its own physical and chemical properties.
Sulfur before being heated in the mixture weighs less and is less reactive than in the heated mixture.

A few physical properties of an iron nail are its mass, volume, and density.
Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.
the color
No. Making mixtures are physical changes and the chemical substances will not change.
It is always categorized as a Physical change as no new substance with different properties forms.
colour is different and so is some others
Neither. Sulfur is an element by it self , that has its own physical and chemical properties.
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.
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.

Earth's physical properties are:Water,Dust,Rock,Air,and Iron
it is iron
No, the sulfur and iron still have their individual properties. Iron is still magnetic and the sulfur can be dissolved by carbon disulfide leaving behind the iron.
