Why there is no substance formed when sulfur and iron is heated?
When sulfur and iron are heated together, they react to form iron sulfide. Iron sulfide is a compound, not a mixture, so it does not show the properties of its individual elements like sulfur and iron. The formation of this compound is a chemical reaction where the atoms of sulfur and iron rearrange to create a new substance with different properties.
When Fe and S are heated togather do they make a mixture ir a compound?
They form a sulfide (compound) and the change is chemical.
What is the difference between a mixturre and a compound?
A mixture is a collection of various elements which have not ionically bonded. A compound is when those elements are heated up and join together. Mixture = Iron and Sulphur Compound = Iron Sulphate
Is heated sulfur and iron fillings is substance or mixtures?

Is a distilled water a mixture?
Distilled water is a pure substance and not a mixture as it consists of a single type of molecule - H2O. It is obtained by the process of distillation, which involves the separation of water molecules from impurities and other substances.
What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
Is a lava lamp a compound or a mixture?
A lava lamp is considered a mixture. It is a combination of oil, water, and wax that behaves as a solution when heated.
What change might you observe after phosphorus and hydrogen react to form the compound phosphine?
When heated, the new substance will turn red.
What happens when dirt and water mixture is heated?
Then the substance in the container becomesa mixture of hot dirt in hot water.
Are elements in a compound heated until they boil?
No, elements in a compound are not necessarily heated until they boil. Boiling point is the temperature at which a substance changes from a liquid to a gas. Heating a compound can be used to separate its components by taking advantage of differences in boiling points through techniques such as distillation or chromatography.
