Use a magnet to lift out the iron filings.
H2 (g) + FeSO4 (s) hydrogen gas and iron sulphate
Gun powder is mixture.
It is a homogenous mixture.
brown powder
The iron fillings are attracted by the magnet and separated from the sulphur powder.
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
Use a magnet to lift out the iron filings.
get a magnet that attracts iron
five examples of mixture are 1.sulphur powder and iron fillings 2.rice and pulse 3.nuts and bolts 4.salt and water 5.sandwich
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
use a kitchen strainer and pour water over the talcum powder nail mixture use a magnet talcum powder is non magnetic
H2 (g) + FeSO4 (s) hydrogen gas and iron sulphate
Heating a mixture of sulfur powder and iron fillings will produce Generation of black iron sulfide (FeS) because of insufficient oxidation of sulfur into the iron oxide +3, and Fe2O3 iron sulfide is black, not yellow over iron sulfide (FeS2) ,can be called pyrite. Use iron fillings and sulphur powder and distinguish between these on the basis of: i) appearance i.e., homogeneity and heterogeneity ii) behavior towards a magnet iii) behavior towards carbon disulphide a solvent iv) effect of heat.
That produces a strongly exothermic reaction that results in the production of a grey substance, an iron sulphide. Please see the link.
you use a magent
Gun powder is always a mixture.
