Question

Why is iron sulphide a compound ?

Answer 1

A chemical compound is a material made up of numerous similar molecules (or molecular entities) that are bound together by chemical bonds and contain atoms from many elements. As a result, a molecule made up of only one element's atoms is not a compound. Compounds are classified into four kinds based on how the component atoms are kept together.

Complete Step By Step Answer:
The elements iron and sulphur are both found in the periodic table. As a result, each has its own set of physical and chemical characteristics. Sulfur is a nonmetal, while iron is a metal. When these two elements are heated together, the iron atoms react with the sulphur atoms to form iron sulphide. A compound differs from an element in that it is created by combining two or more components chemically. Iron sulphide is not the same as iron or sulphur; it is a separate material with its own set of physical and chemical properties. A mixture, on the other hand, is what you get when you combine two or more components without mixing them chemically. When you combine iron with sulphur without adding heat, you get a combination of iron and sulphur. Mixtures vary from compounds in that they may be separated easily. Because iron is attracted to magnets, but sulphur is not, a magnet may be used to separate the iron from the sulphur. Iron sulphide is a combination that can be broken down into the elements iron and sulphur, each of which has its own set of characteristics. The characteristics of a compound differ significantly from those of its component parts.

Note:
A chemical compound is any material that has two or more different types of atoms (chemical elements) in a set stoichiometric proportion; the notion is most easily grasped when discussing pure chemical substances. Chemical compounds may be transformed into compounds or substances with fewer atoms via chemical reaction because they are made up of set proportions of two or more types of atoms. In the chemical formula, the ratio of each element in the compound is given as a ratio.
