The reaction is an example of which of the following reactions?
Explanation of Correct option
(B) Addition/Combination Reactions: It is a union of two or more substances to form a new substance. It may be brought about by the application of heat, light, electricity, or pressure.
In this reaction, two elements are combined to form a single product. This is a combination reaction.
Explanation of Incorrect option
(A) Decomposition Reaction: It is the breaking up of a substance into simpler compounds and it may be brought about by the application of heat, light, electricity etc.
A decomposition reaction brought by heat is known as thermal decomposition.
(D) Displacement Reactions: It involves the displacement of one of the constituents of a compound by another substance and may be regarded as a displacement reaction.
When zinc reacts with sulfuric acid, hydrogen gas is liberated and zinc sulfate is formed.
(C) Double Displacement: It is a mutual exchange of the radicals of two compounds taking part in the reaction and results in the formation of two new compounds.
Hence, option(B) is correct.
