No, without melting they don't react.
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.
Sulfur hexafluoride is a compound composed of sulfur and fluorine elements. It is not an element itself, but rather a molecule made up of multiple atoms bonded together.
YES. Because it is now the combination of 2 phases.
Sulfur and iron filings together are a mixture.
a mixture
Sulfur is an element. Elements are not mixtures.
Sulfur is an element. Elements are not mixtures.
No, it is a mixture, as they are not liquids.
Iron filings and sulfur yellow powder are pure substances, while a mixture of iron and sulfur is a combination of two elements physically mixed together. When iron and sulfur are combined, they can be easily separated by physical means, whereas iron filings and sulfur powder cannot be separated without a chemical reaction. The similarities lie in the chemical elements present (iron and sulfur) in all three substances.
Since Sulfur Trioxide (SO3) is composed of two elements in an ionic bond, it is a binary compound.
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.
The way you phrase that is a little dubious because no mixture is a 'pure substance'. However, compounds like iron sulphide that are actually bonded together areconsidered pure substances. The elements of a mixture are not united by a chemical change and can (in theory) be separated.
