What is produced during the replacement reaction of cu(no3)2 and zn? 1. znno3 + cu 2. zn + cu(no3)2 3. zncu + 2no3 4. zn(no3)2 + cu

 What  is produced  during  the  replacement  reaction  of CU(NO3)2  and zn  is  

    Zn(NO3)2  +Cu (answer 4)

explanation

Replacement  reaction  is  a   type  of  chemical reaction in  which   an  element  react  with  a  compound  and  take the  place  of another  element  in that compound.

 Zn  is  more reactive than  Cu, therefore Zn replaces   cu from   CU(NO3)2  to form  Zn(NO3)2  +Cu
