The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
The hot iron particles oxidize in the presence of the sulfur particles to iron sulfide.
Mixtures are formed from two or more substances.
Rock salt contains all the minerals found in the seawater from which it formed. These will be many, but NaCl will be the main one.
A compound is a simple substance, a mixture is formed from two or more compounds.A mixture can be separated by physical procedures, a compound not.
When one substance is insoluble in another, they form a heterogeneous mixture where the insoluble substance remains separate and distinct within the mixture. This can result in the formation of phases such as suspensions or precipitates, depending on the nature of the substances involved.
yes.
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.
An iron sulfide is obtained: FeS2.
The hot iron particles oxidize in the presence of the sulfur particles to iron sulfide.
A mixture is formed.
This is a mixture.
