Question

What happens when sulphur and iron are heated?

Answer 1

Hint :A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.

Complete Step By Step Answer:
When iron filings and sulphur powder are combined and heated, a chemical reaction occurs, resulting in ferrous sulphide (FeS). It's a brand-new chemical with qualities that aren't seen in Fe or S. As a result, heating a powdered iron and sulphur combination results in a chemical change. Sulphur dioxide, an unpleasant, poisonous, and suffocating gas, may be produced by burning both solid and molten sulphur. It depicts the exothermic reaction of two elements, iron and sulphur, to produce iron sulphide as a compound. When you combine matter in a method that allows the components to be separated again, you've created a mixture. A compound is formed when two or more components combine chemically to generate a new material. For example, you can make a combination out of iron filings and sulphur. To separate the iron from the sulphur, all you need is a magnet. When you heat iron and sulphur together, you get iron sulphide, which is a chemical.
$$Fe+S\to FeS$$

Note :
Iron sulphide, sometimes known as iron sulphide, is a group of chemical compounds made up of iron and sulphur. Iron(II) sulphide, often known as ferrous sulphide, is a chemical compound and mineral having the formula FeS. Non-stoichiometric iron sulphides are frequently iron-deficient. All of the solids are black and insoluble in water.
