Answer :

(a) This is a redox reaction.

(d) This is a redox reaction.

(e) This is a redox reaction.

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

Acid-base reaction : It is defined as the reaction in which an acid and base react to give salt and water as a product.

Precipitation reaction : It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined. The insoluble salt that settle down in the solution is known an precipitate.

(a) $Cl_2+2OH^-\rightarrow Cl^-+ClO^-+H_2O$

This reaction is a redox reaction in which the oxidation state of Cl changes from (0) to (-1) and shows reduction and the oxidation state of Cl changes from (0) to (+1) and shows oxidation.

This reaction a an acid-base reaction in which NH_3 is a base and H^+ is an acid react to give NH_4^+ as a salt.

(d) $4Fe+3O_2\rightarrow 2Fe_2O_3$

This reaction is a redox reaction in which the oxidation state of Fe changes from (0) to (+3) and shows oxidation and the oxidation state of O changes from (0) to (-2) and shows reduction.

(e) $Ca+F_2\rightarrow CaF_2$

This reaction is a redox reaction in which the oxidation state of Ca changes from (0) to (+2) and shows oxidation and the oxidation state of F changes from (0) to (-1) and shows reduction.
