Complete the following equation
ZnSO4+NH4OHZnS{O_4} + N{H_4}OH
A. ZnSO4+3NH4OH→2(NH4)2SO4+Zn(OH)2↓ZnS{O_4} + 3N{H_4}OH \to 2{(N{H_4})_2}S{O_4} + Zn{(OH)_2} \downarrow
B. ZnSO4+2NH4OH→2(NH4)2SO4+Zn(OH)3↓ZnS{O_4} + 2N{H_4}OH \to 2{(N{H_4})_2}S{O_4} + Zn{(OH)_3} \downarrow
C. ZnSO4+3NH4OH→(NH4)2SO4+Zn(OH)3↓ZnS{O_4} + 3N{H_4}OH \to {(N{H_4})_2}S{O_4} + Zn{(OH)_3} \downarrow
D. ZnSO4+2NH4OH→(NH4)2SO4+Zn(OH)2↓ZnS{O_4} + 2N{H_4}OH \to {(N{H_4})_2}S{O_4} + Zn{(OH)_2} \downarrow

Explanation

Solution

A chemical reaction in which one reactant breaks down into two or more products is known as a decomposition reaction. A double decomposition reaction occurs when two constituent reactants exchange positive and negative ions to generate two new compounds.

Complete answer:
Zinc sulphate reacts with ammonium hydroxide to give ammonium sulphate and zinc hydroxide. White gelatinous precipitate of zinc hydroxide is formed.
The reaction takes place as follows:
ZnSO4+2NH4OH→(NH4)2SO4+Zn(OH)2↓ZnS{O_4} + 2N{H_4}OH \to {(N{H_4})_2}S{O_4} + Zn{(OH)_2} \downarrow
In this reaction, ions of sulphate and ammonia are exchanged. Hence, it is a double decomposition reaction.
Hence, the correct option is D. ZnSO4+2NH4OH→(NH4)2SO4+Zn(OH)2↓ZnS{O_4} + 2N{H_4}OH \to {(N{H_4})_2}S{O_4} + Zn{(OH)_2} \downarrow
Additional Information: The three primary types of decomposition reactions are:
Thermal Decomposition reaction: A decomposition reaction that is activated by thermal energy is known as a thermal decomposition reaction.
Electrolytic Decomposition Reaction: The activation energy for decomposition in an electrolytic decomposition reaction is delivered in the form of electrical energy.
Photo Decomposition Reaction: A photodecomposition reaction is a sort of decomposition reaction in which the reaction absorbs energy from photons and breaks down into its parts.
Applications of Decomposition Reactions:
Cement or calcium oxide production.
Extraction of metals from oxides, chlorides, and other metallurgical processes
Acid indigestion is relieved.
Welding with thermite.

Note:
A solution of ammonia in water has the chemical formula NH4OHN{H_4}OH . Ammonia water, ammonium hydroxide, ammonia liquor, and aqueous ammonia are all names for the same solution. The symbol NH3(aq)N{H_3}(aq) is frequently used to represent NH4OHN{H_4}OH .Ammonium Hydroxide is exceedingly harmful if it comes into contact with the skin and when it comes into contact with the eyes .
