Chapter 4, Problem 56a
Using the activity series (Table 4.5), write balanced chemical equations for the following reactions. If no reaction occurs, write NR. (a) Nickel metal is added to a solution of copper(II) nitrate
Verified step by step guidance1
Identify the reactants: Nickel (Ni) metal and copper(II) nitrate (Cu(NO_3)_2) solution.
Write the unbalanced chemical equation for the potential single displacement reaction: Ni(s) + Cu(NO_3)_2(aq) -> Cu(s) + Ni(NO_3)_2(aq).
Consult the activity series to determine if nickel can displace copper. Nickel must be higher than copper in the activity series for the reaction to occur.
If nickel is higher than copper in the activity series, balance the chemical equation by ensuring the number of atoms of each element is equal on both sides.
If nickel is not higher than copper in the activity series, write 'NR' to indicate that no reaction occurs.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Activity Series
The activity series is a list of metals ranked by their ability to displace other metals from solutions of their ions. Metals higher in the series can displace those lower in the series. This concept is crucial for predicting whether a reaction will occur when a metal is added to a solution containing another metal's ions.

Activity Series Chart
Single Replacement Reaction
A single replacement reaction occurs when one element replaces another in a compound. In the context of the activity series, if a more reactive metal is introduced to a solution containing a less reactive metal's ions, a reaction will take place, resulting in the formation of a new compound and the release of the less reactive metal.
Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both sides of the equation. This is essential for accurately representing the conservation of mass during a chemical reaction. In the case of a reaction or no reaction, the balanced equation reflects the stoichiometry of the reactants and products involved.
