If MnSO4 → Mno + SO3 is not a synthesis reaction, then what type of reaction is it?

A) combustion

B) decomposition

C) double-displacement

D) single-displacement

Decomposition

Explanation:

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.

Since there is only one reactant and it is broken into smaller components,

it is not a synthesis reaction.

A decomposition reaction is a type of chemical reaction in which one reactant yields two or more products.

Since in our question, there is one reactant and it is broken to yield two products, it is a decomposition reaction.
