A student heated a mixture of iron filings and sulphur strongly.she saw a red glow spread through the mixture as the reaction continued.In the end a black solid has been formed according to the following reaction. Fe+S➝FeS
Answers
Answer:
When iron filings are heated with sulfur, the following chemical reaction occurs:
Fe + S --> FeS
Explanation:
The reaction occurring between iron and sulfur is an exothermic reaction and only requires to be heated strongly initially to start the chemical reaction. The red glow that can be seen is a result of the heat that is released when the iron and sulfur combine to form iron sulfide. After all the sulfur and iron has reacted the iron sulfide left is a black colored substance. Iron sulfide has chemical properties of its own which are distinct from the chemical properties of both iron as well as the chemical properties of sulfur.
Answer:
This demonstration or class experiment shows the exothermic reaction of two elements, iron and sulfur, to form the compound, iron sulfide. The two solids are mixed and heated in a test tube (or ignition tube). The reaction can be used to illustrate elements, mixtures and compounds
This reaction can be carried out as a demonstration or class experiment in a well ventilated laboratory provided that the instructions provided here are strictly adhered to.
The reaction can be carried out in borosilicate glass test tubes as a demonstration or in smaller (ignition) tubes by students. The reaction provides an opportunity to show that the properties of a compound are different from its constituent elements.
The reaction must not be carried out on tin lids in the open laboratory as is suggested in some sources. The sulfur may boil or burn releasing sulfur dioxide which is a TOXIC and CORROSIVE gas and may trigger an asthmatic attack.
