Question

Part A
Fe(s)+S(s) →
Heat
FeS(s)
FeS+2HCl(aq)→FeCl 2
​ +H 2
​ S
Part B
Fe(s)+S(s)→ Mixture of iron filings and sulphur
When dilute HCl is added to it.
Fe(s)+S(s)+2HCl(aq)→FeCl 2
​ +H 2
​ + S Sulphur remains unreacted. H 2
​ S gas formed has a foul smell and on passing through lead acetate solution, it turns the solution black. Hydrogen gas burns with a pop sound.

Answer 1

Answer:

f you heat iron filings ans sulphur to a sufficiently high temperature you form iron sulphide

Fe+S→FeS

If you add HCl to this the following reaction occurs:

FeS+2HCl→FeCl

2

+H

2

S

H

S gas is given off and iron chloride is produced.

Both are chemical compounds.
