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.
a)write a word equation for the reaction mentioned above.
b)what does the red glow indicate.
c)State two difference between Mixture (Iron and Sulphur)and the black solid compound formed in the given reaction.
Answers
Answer:
combination reaction
change the colour of reactant due to reaction
Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.
Explanation:
hope u will be satisfied
plz mark as brilliant 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

The sulfur may boil or burn releasing sulfur dioxide which is a TOXIC and CORROSIVE gas and may trigger an asthmatic attack.
