What type of reaction does each of the following equations represent?
vekshin1

Answer:

Option C. Decomposition

Explanation:

To know which option is correct, it is important we know what is a single displacement reaction, double displacement reaction and decomposition reaction.

A Single displacement reaction can be defined as a reaction in which a single element is replaced by another element in a compound.

A double displacement reaction is a reaction involving the exchange of ions of two parts of ionic compounds to form two different compounds.

A decomposition reaction is a reaction in which a compound splits into two or more simpler compound or element.

Bearing the above definitions in mind and considering the question given above, we can conclude that the reaction given in the question above is a decomposition reaction since the compound (NH₄OH) splits into two different compound (NH₃ and H₂O)
