The following reactions: Pb2+ + 2I– → PbI2 2Ce4+ + 2I– → I2 + 2Ce3+ HOAc + NH3 → NH4+ + OAc– are examples of

a. acid-base reactions
b. unbalanced reactions
c. precipitation, acid-base, and redox reactions, respectively
d. redox, acid-base, and precipitation reactions, respectively
e. precipitation, redox, and acid-base reactions, respectively

Answer : The correct option is, (e) precipitation, redox, and acid-base reactions, respectively

Explanation :

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.

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

Acid-base reaction : It is a type of reaction in which an acid is substance that donate hydrogen ions and a base is substance that accepts hydrogen ions.

(1)

This reaction is a precipitation reaction in which two soluble reactants combine to form one soluble products and one insoluble products.

(2)

This reaction is a redox reaction in which cesium shows reduction by gaining electrons and iodine shows oxidation by losing electrons.

(3)

This reaction is an acid-base reaction in which an acid (HOAc) is substance that donate hydrogen ions and a base (NH₃) is substance that accepts hydrogen ions.

the answer is a and have a great day
