Answer:
When iron and sulphur powder are heated together in a dish, there'll be a red glow indicating that a reaction is taking place. After the reaction, a black compound, iron(II) sulphide (FeS) is formed. The reaction is quite strongly exothermic, which means it gives out heat.
✨✨1. When iron filings and sulphur powder are mixed and heated, this would result in a chemical reaction leading to the formation of black ferrous sulphide. ✨✨
✨✨2. When HCL is added to iron : -
When dilute Hydrochloric acid is added to iron filings, iron chloride & hydrogen gas are produced. In this reaction, iron displaces hydrogen from hydrochloric acid to form iron chloride and hydrogen gas. The reaction can be represented as: Fe + 2HCl⟶FeCl2 + H2
As part 'A' is heated, a compound FeS is formed by the reaction between iron filings and sulphur. When dilute HCI is added to part A, FeS will react with dil HCI to form H2S gas which has smell of rotten eggs and will turn lead acetate paper black. ✨✨
