When sulfur and iron are heated together Fe and sulphur ions are formed. These ions make FeS together. FeS is black in color.
pure substance
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
Iron filings and sulfur together form a mixture, not a compound. A compound is a substance formed by the chemical combination of two or more elements in a fixed ratio, while a mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.
Iron filings may be pure elemental iron, it depends on the source of the iron.
Yes, solid sulfur mixed with iron filings is a heterogeneous mixture. A heterogeneous mixture consists of two or more substances that are visibly distinguishable from each other. In this case, you can physically see and separate out the sulfur and iron filings.
Sulfur and iron filings together are a mixture.
The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
pure substance
No
yes.
Salt is a chemical compound known as sodium chloride, which is formed by the combination of sodium and chloride ions. It is not a mixture but rather a pure substance with a fixed chemical composition.
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.
a compound is a substance containing 2 or more different types of elements while a mixture is a substance containing 2 or more different materials. ------------------------------------------------------------------ The components of a compound can not be separated by physical means, the components of a mixture can be separated by physical means.

It is a mixture
No, iron filings are not a mixture
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
