Single Displacement Chemistry Example 2

Solution

1. 1
   Since Cu is more reactive than Ag, copper will displace silver from solution.
2. 2
   Unbalanced: $\text{Cu} + \text{AgNO}_3 \rightarrow \text{Cu(NO}_3)_2 + \text{Ag}$.
3. 3
   Cu forms $\text{Cu}^{2+}$, needing 2 $\text{NO}_3^-$, so 2 AgNO$_3$ are needed.
4. 4
   Balanced: $\text{Cu} + 2\text{AgNO}_3 \rightarrow \text{Cu(NO}_3)_2 + 2\text{Ag}$.
