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.
Iron sulfide is a compound.
Assuming you mean ZnS, it's a compound - Zinc sulfide.
Sulfur is an element. Sulfide, the ion formed by sulfur cannot exist on its own as a substance because it carries a negative charge and must be accompanied by a positive ion.
The name of the chemical compound CuS is copper (II) sulfide.
Cadmium sulfide It is a compound of Cadmium (Cd) and Sulphur (S).
Sodium sulfide (Na2S) is a compound.
Iron sulfide is a compound.
The formula is Ag2S, but this is a compound, not a mixture.
Iron sulfide is a pure compound. It can be as in aqueous medium too as a solution.
Assuming you mean ZnS, it's a compound - Zinc sulfide.
They form a sulfide (compound) and the change is chemical.
It is neither a mixture nor an element. Copper sulphate (CuSO4) is a COMPOUND. A compound is a substance consisting of atoms, which are combined together using the electrons in their outer most energy shells. As a compound it is composed of atoms of three different elements. viz., 1 atom x copper (Cu) 1 atom x Sulphur (S) 4 atoms x Oxygen (O) Mixtures do NOT use their respective electrons.
Silver sulfide is a compound because it is made up of a specific ratio of silver and sulfur atoms chemically bonded together. It has a fixed composition and properties distinct from its constituent elements.
No, hydrogen sulfide is a pure substance, specifically a compound, composed of hydrogen and sulfur atoms. It is not a heterogeneous mixture, which is a combination of different substances that are not uniformly mixed.
When a mixture of powdered iron and sulfur is heated, iron sulfide is formed. Iron sulfide is a compound composed of iron and sulfur atoms that have reacted together through a chemical reaction.
sodium and sulfide
Iron sulfide is an inorganic compound formed from the elements iron and sulfur. It is classified as a binary compound, specifically a metal sulfide.
