Molten Iron is not a mixture because it is still iron. Melting is a physical change meaning that the chemical makeup of the iron is not changed. Its still the element iron.
No, molten iron is a pure substance because it is composed of only one type of element, which is iron. Unlike mixtures which contain two or more different substances mixed together, molten iron has a uniform composition.
Iron is an element. It is a pure substance that consists of only one type of atom, specifically iron atoms.
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.
No, iron metal is not a solution. A solution is a homogenous mixture where one substance is dissolved in another. Iron metal is a pure substance composed of iron atoms.
Iron sulfide is a pure compound. It can be as in aqueous medium too as a solution.
No, molten iron is a pure substance because it is composed of only one type of element, which is iron. Unlike mixtures which contain two or more different substances mixed together, molten iron has a uniform composition.
An element - substance - NOT a mixture.
substance
I just learned this but forgot lol
Mixture
Mixture
Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
Iron is an element. It is a pure substance that consists of only one type of atom, specifically iron atoms.
An iron sulfide is obtained: FeS2.
Without a chemical reaction this is a mixture.
