Dissolve the sulphur in carbon disulphide and pour the liquid off the copper. Evaporate the liquid to yield the sulphur.
step on it and spit on it
I want the answer
no it is a chemical change
Sulfur powder will float on the surface of the water.
A White Powder.... I know this is correct because I just took a test with this question, its in front of me, and its correct! lolz =) hope this helps
Copper Sulfide
step on it and spit on it
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.
I want the answer
you use a magent
Iron powder is attracted by a magnet, sulfur is dissolved in carbon disulfide, but be careful: it is explosive, toxic and stinks (rotten cauliflower)
no it is a chemical change
no it is a chemical change
By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
Use a magnet to lift out the iron filings.
There is no compound as copper sulfur, but copper sulfate is a compound, yes.
yes
