Solution

Solution Steps

Step 1: Identify the Reactants and Products

In the given single displacement reaction, chlorine ($\mathrm{Cl}_2$) is reacting with sodium iodide ($\mathrm{NaI}$) to produce iodine ($\mathrm{I}_2$) and sodium chloride ($\mathrm{NaCl}$).

Step 2: Write the Unbalanced Chemical Equation

The unbalanced chemical equation for the reaction is:

\[ \mathrm{Cl}_2 + \mathrm{NaI} \rightarrow \mathrm{I}_2 + \mathrm{NaCl} \]

Step 3: Balance the Chemical Equation

To balance the equation, ensure that the number of each type of atom is the same on both sides of the equation.

Chlorine (Cl): There are 2 chlorine atoms on the left side ($\mathrm{Cl}_2$), so we need 2 $\mathrm{NaCl}$ on the right side.
Iodine (I): There are 2 iodine atoms on the right side ($\mathrm{I}_2$), so we need 2 $\mathrm{NaI}$ on the left side.
Sodium (Na): With 2 $\mathrm{NaI}$ on the left, we have 2 sodium atoms, which matches the 2 $\mathrm{NaCl}$ on the right.

The balanced chemical equation is:

\[ \mathrm{Cl}_2 + 2\mathrm{NaI} \rightarrow \mathrm{I}_2 + 2\mathrm{NaCl} \]
