How do you separate sulfur from mixture of carbon particles and powdered roll sulfur?
By the process of diffusion.....
How could you separate a mixture of iron fillings and sulfur powder?
Use a magnet to lift out the iron filings.
What is formed when a mixture of powdered iron and sulfur is heated?
iron sulfide, FeS or Fe3S2
What type of change is it when you heat a mixture of powdered iron and sulfur iron?
It is a chemical reaction
What substance can be used to separate a mixture of iron fillings and powdered sulfur?
a magnet
Is iron filings and powdered sulfur a homogeneous mixture?
No, the mixture of powdered sulfur and iron filling are not a homogenous mixture, they are a heterogenous mixture.
What kind of mixture is sulfur and iron fillings?
it is a heterogenous mixture
Is powdered sulfur and iron filling a mixture or a solution?
a mixture
How do you separate sulfur from mixture of carbon particles and powdered roll sulfur?
By the process of diffusion.....
What would happen if you pass a magnet over a mixture of iron fillings and sulfur powder?
The iron fillings are attracted by the magnet and separated from the sulphur powder.
What distinguishes a compound like copper sulfide from an ordinary mixture of copper powder and sulfur?
Copper Sulfide is a wholly different chemical from copper and sulfur, and thus shows different characteristics and is not dividable by physical means, while a mixture of copper and sulfur powder is just a physical mix.
How could you separate a mixture of iron fillings and sulfur powder?
Use a magnet to lift out the iron filings.
What is formed when a mixture of powdered iron and sulfur is heated?
iron sulfide, FeS or Fe3S2
What type of change is it when you heat a mixture of powdered iron and sulfur iron?

Why is the law of conservatoion not obeyed in this reaction of iron fillings heated in the mixture with sulfur?
I think that this law is obeyed in this simple reaction.
Why the mixture of the metal fillings and sulfur becomes chemical change when heat was applied?
Applying heat to the mixture causes a chemical reaction to occur: 2Fe + 3S -> Fe2S3
