Answer:

The answer to your question is 6

Explanation:

Data

              Cu  +  2AgNO₃   ⇒  

To find the answer, count the number of each element in the reactants

Element                Quantity

Copper                        1

Silver                           2

Nitrogen                      1

Oxygen                        6

Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
