Below are given two chemical reactions :
(i) `2KBr(aq)+Cl_(2)(aq)toMgCl_(2)(aq)+H_(2)(g)`
(ii) `Fe(s)+S(s)toFeS(s)`
Which is combination reaction and which is displacement reaction ?

Text Solution

Verified by Experts

(i) In the first reaction, potassium bromide solution reacts with chlorine solution to form potassium chloride solution and bromine. So in this reaction, chlorine is displacing bromine from potassium bromide to from potassium chloride and bromine is set free. Thus, it is a displacement reaction.
(ii) In the second reaction, iron combines with sulphur to from iron (II) suphide. So, it is a combination reaction.
