What product is made when you mix copper turnings and sulphur powder?
Copper sulfides, but only after heating the mixture.
Does heating copper II sulfate produce a chemical change or physical change?
Heating Copper Sulfate gently drives off the water of crystallization leaving an amorphous white powder. This is purely a physical reaction. Heating this powder strongly will cause a chemical reaction liberating sulfur dioxide and oxygen, leaving black copper(II)oxide: 2CuSO4 >2CuO + 2SO2 + O2
What problems happens when heating copper sulfide in air?
Heating copper sulfide in air can result in the copper sulfide being oxidized to form copper oxide and sulfur dioxide gas. This process may produce toxic sulfur dioxide fumes which can be harmful if inhaled. Additionally, the copper oxide formed may have different properties compared to copper sulfide, affecting its intended applications.
What substance is formed when heating sulfur powder and iron fillings?
A black solid called iron sulfide is formed when heating sulfur powder and iron fillings together. This is a chemical reaction between the sulfur and iron that results in the formation of the iron sulfide compound.
What happen when iron filling is heated with sulfur powder?
Heating iron filings with sulfur powder will result in a chemical reaction known as a thermite reaction. This reaction produces iron sulfide and a significant amount of heat and light. The iron sulfide formed is a black compound.
Heating a crystal of blue copper sulfate yields a black powder a hydrate a white powder or sulfur?
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.
What product is made when you mix copper turnings and sulphur powder?
Copper sulfides, but only after heating the mixture.
Is copper powder behaves like iron powder when it mixed with sulfur?
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.
How do you separate copper strips from sulfur powder?
To separate copper strips from sulfur powder, you can use a process called filtration. Mix the copper strips and sulfur powder with water to form a mixture. Then, pass the mixture through a filter paper to separate the solid copper strips from the sulfur powder, which will remain in the filter paper.

Additionally, the copper oxide formed may have different properties compared to copper sulfide, affecting its intended applications.
What happens when you heat sulfur and copper together?
When you heat sulfur and copper together, they will react to form copper sulfide. This reaction occurs due to the high reactivity of sulfur with metals like copper. Copper sulfide is a black solid compound that is formed as a result of the combination of copper and sulfur atoms during the heating process.
What substance is formed when heating sulfur powder and iron fillings?
A black solid called iron sulfide is formed when heating sulfur powder and iron fillings together. This is a chemical reaction between the sulfur and iron that results in the formation of the iron sulfide compound.
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.
What happen when iron filling is heated with sulfur powder?
Heating iron filings with sulfur powder will result in a chemical reaction known as a thermite reaction. This reaction produces iron sulfide and a significant amount of heat and light. The iron sulfide formed is a black compound.
How do you make copper-sulfide?
Copper sulfide can be made by reacting copper and sulfur or by heating copper oxide with sulfur at high temperatures. The reaction forms various copper sulfide compounds such as cuprous sulfide (Cu2S) or cupric sulfide (CuS).
Color sulfur after heat or burn?
Sulfur or sulphur turns a golden brown as the yellow powder starts to melt when heated. The longer the heating, the darker the bubbling sulfur or sulphur will become.
