To determine whether a reaction occurs between copper (Cu) and nickel(II) nitrate (Ni(NO3)2), and to predict the products, we can refer to the Activity Series of Elements. The Activity Series ranks elements based on their reactivity, particularly their ability to displace other elements from aqueous solutions of their compounds.
1. Activity Series Understanding:
- In the Activity Series, more reactive metals can displace less reactive metals from their compounds.
- If an element is higher in the series, it can replace an element lower in the series from a compound.
2. Identifying the Placement in the Activity Series:
- Copper (Cu) is lower in the Activity Series than Nickel (Ni). This means that copper is less reactive compared to nickel.
3. Predicting the Reaction:
- Since copper is less reactive than nickel, copper cannot displace nickel from its compound (nickel(II) nitrate, Ni(NO3)2). Copper won’t be able to replace nickel in the nitrate solution.
4. Conclusion:
- Given that copper is less reactive than nickel based on their positions in the Activity Series, no reaction will occur when solid copper is placed in a solution of nickel(II) nitrate.
Thus, the correct answer to the question is:
C. No reaction will occur.
