Dissolve the sulphur in carbon disulphide and pour the liquid off the copper. Evaporate the liquid to yield the sulphur.
When copper powder is mixed with sulfur, it does not react in the same way as iron powder does. Copper and sulfur do not have a strong affinity for each other, so they typically do not react vigorously like iron and sulfur do, which form iron sulfide. Copper sulfide is a more stable compound that can be formed under specific conditions.
One common method to separate sulfur powder is by using a process called filtration. This involves passing a mixture of sulfur powder and a solvent through a filter, with the sulfur powder remaining on the filter while the solvent passes through. The collected sulfur powder can then be dried to obtain the separated solid.
No, using oxygen to separate molten copper sulfide into copper and sulfur dioxide is a chemical change because new substances with different chemical properties are formed. This process involves a chemical reaction where the copper sulfide is broken down into copper and sulfur dioxide molecules.
The hypothesis for separating iron filing and sulfur powder using a magnet is that iron is a magnetic material, whereas sulfur is not. By using a magnet, we can separate the iron filings from the sulfur powder based on their magnetic properties.
Heating a crystal of blue copper sulfate typically results in the release of water vapor, leaving behind white anhydrous copper sulfate powder. The black powder formed may be due to decomposition of the copper sulfate or impurities in the crystal. Sulfur may not be directly produced from heating copper sulfate.
Heating copper wire and sulfur powder together will result in the formation of copper sulfide. Copper sulfide is a compound where copper and sulfur atoms are chemically bonded together.

One way to separate iron powder and sulfur powder is by using a magnet. Since iron is magnetic, you can attract and separate the iron powder from the sulfur powder. Another method is to use a technique called sublimation, where the sulfur powder is heated to convert it into a gas, leaving behind the iron powder.

you use a magent
You can use a magnet to separate the iron fillings from the sulfur powder. The iron fillings will be attracted to the magnet, allowing you to easily separate them from the sulfur powder.
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.
Filtration can be used to separate copper sulfate from sulfur because copper sulfate is soluble in water, while sulfur is not. By adding water to the mixture and then filtering, the insoluble sulfur will remain on the filter paper, while the soluble copper sulfate will pass through as part of the filtrate.
No, using oxygen to separate molten copper sulfide into copper and sulfur dioxide is a chemical change because new substances with different chemical properties are formed. This process involves a chemical reaction where the copper sulfide is broken down into copper and sulfur dioxide molecules.
no it is a chemical change
Copper sulfides, but only after heating the mixture.
One method is to use a magnet to separate the iron fillings from the sulfur powder, as iron is magnetic but sulfur is not. Another method is to mix the mixture with a solvent that dissolves the sulfur powder, leaving the iron fillings behind. Lastly, heating the mixture can also cause the sulfur to sublimate, leaving the iron fillings behind.
