a chemical change occurs
When iron and sulfur combine to form iron sulfide, a chemical reaction occurs. Iron atoms react with sulfur atoms to form a new compound with different physical and chemical properties than the original elements. The iron and sulfur lose their individual characteristics and combine to create a new substance, iron sulfide.
Evidence of a chemical change occurring when iron and sulfur combine to form iron sulfide includes the observation of color change from gray/brownish to black, the release of heat energy as the reaction occurs, and the formation of a new substance with different properties than the original iron and sulfur. Additionally, the mass of the iron sulfide formed would be equal to the combined masses of the iron and sulfur used in the reaction, as mass is conserved in chemical reactions.
When sulfur is heated with iron fillings, a chemical reaction takes place where sulfur and iron combine to form iron sulfide. This reaction involves the transfer of electrons from the iron to the sulfur, leading to the formation of a new compound with different properties than the original elements.
Heating iron and sulfur causes a chemical reaction to occur, resulting in the formation of iron sulfide, a new substance with different properties than the original elements. The change in color, from the original yellow of sulfur and silver-gray of iron, and the change in magnetic properties indicate a chemical change has taken place.
Iron is a magnetic substance, which means it is attracted by a magnet. On the other hand, Sulfur is a non-magnetic substance. If you place a magnet near a mixture of Iron and Sulfur, the iron pieces will stick to the magnet, while the sulfur powder will remain.
When iron and sulfur combine to form iron sulfide, a chemical change takes place. This reaction is characterized by the formation of a new substance with different properties from the original iron and sulfur, including a change in color and the release of energy in the form of heat.

Evidence of a chemical change between iron and sulfur to form iron sulfide includes color change (from grey to black), formation of a new substance with different properties, and the release of heat energy during the reaction. Additionally, chemical analysis showing the presence of iron and sulfur atoms in the product confirms a chemical transformation has taken place.

When sulfur reacts with HCl (hydrochloric acid), a chemical reaction takes place producing hydrogen sulfide gas (H2S) and sulfur dichloride (S2Cl2) as products. The reaction can be represented by the following equation: S + 2HCl -> H2S + S2Cl2.
Contact between silver coins and sulfur can cause tarnishing of the silver due to a chemical reaction between the two materials. Sulfur reacts with the silver to form silver sulfide, which appears as a black tarnish on the surface of the coins. It is best to keep silver coins stored in a cool, dry place away from sulfur-containing materials to prevent tarnishing.
Definite composition, and a chemical change occurring when the components are mixed. A compound of Iron(II) sulfide is more than just mixing equal amounts of molecules of iron and sulfur. Mix 5.6 g iron and 3.2 g sulfur and they are not a compound. The iron can be separated using a magnet. Heat and allow a chemical change to take place and they cannot be easily separated, the magnet won't separate the iron now.
