Understanding Single Replacement Reactions

Single replacement reactions are a type of chemical reaction where one element replaces another element in a compound. These reactions are also known as single displacement reactions. In a single replacement reaction, one element takes the place of another element in a compound, resulting in the formation of a new compound.

The Reaction Between Sodium Chloride and Fluorine

The reaction between sodium chloride (NaCl) and fluorine (F2) is a classic example of a single replacement reaction. The unbalanced equation for this reaction is:

${ NaCl + F_2 \rightarrow NaF + Cl_2 }$

However, this equation is not balanced. To balance the equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides.

Balancing the Equation

To balance the equation, we need to add coefficients in front of the formulas of the reactants or products. The balanced equation for the reaction between sodium chloride and fluorine is:

${ 2 NaCl + F_2 \rightarrow 2 NaF + Cl_2 }$

However, this is not the only possible balanced equation. We can also write the balanced equation as:

${ 2 NaCl + F_2 \rightarrow 2 NaF + Cl_2 }$

${ NaCl + F_2 \rightarrow NaF + Cl_2 }$

But which one is the correct balanced equation?

Analyzing the Options

Let's analyze the options given:

A. $${ 2 NaCl + F_2 \rightarrow NaF + Cl_2 }$$

B. $${ NaCl + F_2 \rightarrow NaF + Cl_2 }$$

C. $${ 2 NaCl + F_2 \rightarrow 2 NaF + Cl_2 }$$

D. $${ NaCl + F_2 \rightarrow NaF + Cl_2 }$$

Evaluating the Options

To determine the correct balanced equation, we need to consider the law of conservation of mass. This law states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element must be the same on both the reactant and product sides.

Option A: $${ 2 NaCl + F_2 \rightarrow NaF + Cl_2 }$$

This equation is not balanced because the number of sodium (Na) atoms is not the same on both sides. There are 2 sodium atoms on the reactant side, but only 1 sodium atom on the product side.

Option B: $${ NaCl + F_2 \rightarrow NaF + Cl_2 }$$

This equation is not balanced because the number of chlorine (Cl) atoms is not the same on both sides. There is 1 chlorine atom on the reactant side, but 2 chlorine atoms on the product side.

Option C: $${ 2 NaCl + F_2 \rightarrow 2 NaF + Cl_2 }$$

This equation is balanced because the number of atoms of each element is the same on both the reactant and product sides. There are 2 sodium atoms on both sides, 2 chlorine atoms on both sides, and 2 fluorine atoms on both sides.

Option D: $${ NaCl + F_2 \rightarrow NaF + Cl_2 }$$

This equation is not balanced because the number of chlorine (Cl) atoms is not the same on both sides. There is 1 chlorine atom on the reactant side, but 2 chlorine atoms on the product side.

Conclusion

Based on the analysis of the options, the correct balanced equation for the reaction between sodium chloride and fluorine is:

${ 2 NaCl + F_2 \rightarrow 2 NaF + Cl_2 }$

This equation is balanced because the number of atoms of each element is the same on both the reactant and product sides. Therefore, option C is the correct answer.
