pure substance
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.
An iron frying pan is made of iron, which is an element. Therefore, the iron frying pan is not a mixture or a compound, but rather a pure element.
Iron filings may be pure elemental iron, it depends on the source of the iron.
Anything that appears on the periodic table is a pure substance called an element. Uranium appears on the periodic table with the atomic number 92, it is therefore an element.
When you mix Iron filings and Sulphur crystals together, you form a mixture of Iron and Sulphur from which both the components can be separated by physical means. But if you heat the mixture strongly, then it becomes a compound of Iron Sulphide from which the two components cannot be separated by physical means.
Iron is a chemical element; sand may be a compound or a mixture.
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
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.

in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
Iron filings just means metallic iron, shredded into little bits. It's an element, not a mixture.
An iron frying pan is made of iron, which is an element. Therefore, the iron frying pan is not a mixture or a compound, but rather a pure element.
It is a compound.
Iron is a chemical element.
