Cu(no3)2 + zn(s) → cu (s) + zn(no3)2 is an example of which type of reaction

Cu(NO3)2 + Zn (s) → Cu (s) + Zn(NO3)2 is an example of single displacement reaction.

DISPLACEMENT REACTION:

A displacement reaction is a type of reaction in which one element is replaced by another element in a compound. A displacement reaction can either be single or double depending on the number of elements that was displaced or replaced. In the reaction as follows:

Cu(NO3)2 + Zn (s) → Cu (s) + Zn(NO3)2

Copper (Cu) is displaced or replaced by Zinc (Zn) in the nitrate compound. Since, it involves only one displacement, it is termed a single displacement reaction.
