What evidence indicates that a chemical change took place when the iron and sulfur combined to from iron sulfur?
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.
What change takes place when iron and sulfur combine to form iron sulfide?
When iron and sulfur combine to form iron sulfide, a chemical reaction occurs where iron atoms lose electrons to sulfur atoms, forming a compound with a new chemical structure. This reaction is exothermic, releasing energy in the form of heat.
Does iron and sulfur react when they are heated?
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.
Why iron sulfur are heated and form a non magnetic shiny grey substance is chemical change?
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.
What happen when sulfur is heated with iron fillings?
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.

What evidence indicates that a chemical change took place when the iron and sulfur combined to form iron sulfide?
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 iron and sulfur combine to form iron sulfide what change takes place?
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.

What happens when Sulphur reacts with HCl?
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.
Silver coins and sulfur?
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.
What is the differentiates between a Compound and a mixture?
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.
What happens when sulfuric acid is combined with Iron hydroxide?
If you simply mix iron filings and sulfur crystals together, you get a mixture. The iron keeps the properties of iron (including its ability to be magnetized), and the sulfur retains the properties of sulfur. This mixture can be easily separated mechanically by simply passing a magnet nearby, which will magnetize and attract the iron filings. If you combine the two using heat, however, they iron and sulfur will chemically react to form the compound iron sulfide. This compound will have properties different from either the sulfur or iron. A magnet will no long separate the two (although it might attract excess iron that was not combined in the reaction). This experiment is meant to distinguish the properties of substances combined in mixtures versus substances combined as chemical compounds.
What is a substance when formed two or more substances are combined and a chemical change takes place?
a compound
