**Balancing Chemical Equations: A Step-by-Step Guide**

Understanding the Given Unbalanced Chemical Equation

The given unbalanced chemical equation is $BF_3 + Li_2SO_3 \rightarrow B_2(SO_3)_3 + LiF$ . This equation represents the reaction between boron fluoride ( $BF_3$ ) and lithium sulfite ( $Li_2SO_3$ ) to form boron sulfite ( $B_2(SO_3)_3$ ) and lithium fluoride ( $LiF$ ). However, the equation is not balanced, meaning that the number of atoms of each element is not equal on both the reactant and product sides.

The Importance of Balancing Chemical Equations

Balancing chemical equations is a crucial step in chemistry as it ensures that the law of conservation of mass is obeyed. This law states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element must be equal on both the reactant and product sides of the equation.

Step 1: Counting the Number of Atoms of Each Element

To balance the equation, we need to count the number of atoms of each element on both the reactant and product sides. Let's start with the elements that appear only once in the equation: boron (B), lithium (Li), and fluorine (F).

On the reactant side, there is 1 boron atom, 2 lithium atoms, and 3 fluorine atoms.
On the product side, there is 2 boron atoms, 1 lithium atom, and 1 fluorine atom.

Step 2: Balancing the Boron Atoms

To balance the boron atoms, we need to multiply the boron-containing compound ( $BF_3$ ) by a coefficient that will give us 2 boron atoms on the product side. Since there is 1 boron atom in $BF_3$ , we need to multiply it by 2.

Step 3: Balancing the Lithium Atoms

Now that we have 2 boron atoms on the product side, we need to balance the lithium atoms. Since there are 2 lithium atoms on the reactant side, we need to multiply the lithium-containing compound ( $Li_2SO_3$ ) by a coefficient that will give us 2 lithium atoms on the product side. However, we also need to consider the sulfite group ( $SO_3$ ) that is attached to the lithium atom. Since there is 1 sulfite group on the reactant side, we need to multiply it by 2 as well.

Step 4: Balancing the Fluorine Atoms

With the boron and lithium atoms balanced, we need to balance the fluorine atoms. Since there are 3 fluorine atoms on the reactant side, we need to multiply the fluorine-containing compound ( $BF_3$ ) by a coefficient that will give us 3 fluorine atoms on the product side. However, we already multiplied $BF_3$ by 2 in step 2, so we need to multiply it by 3/2 to get 3 fluorine atoms.

Step 5: Balancing the Sulfite Group

Finally, we need to balance the sulfite group ( $SO_3$ ). Since there are 2 sulfite groups on the product side, we need to multiply the sulfite-containing compound ( $Li_2SO_3$ ) by a coefficient that will give us 2 sulfite groups on the product side.

The Balanced Chemical Equation

After following these steps, we can write the balanced chemical equation as:

$2BF_3 + 3Li_2SO_3 \rightarrow B_2(SO_3)_3 + 6LiF$

Conclusion

In conclusion, the coefficient of lithium fluoride ( $LiF$ ) in the balanced chemical reaction is 6. This is because we multiplied the lithium-containing compound ( $Li_2SO_3$ ) by a coefficient of 3 to balance the lithium atoms, and there is 1 lithium atom in $LiF$ . Therefore, the correct answer is C. 6.

Discussion and Analysis

The balanced chemical equation shows that the reaction between boron fluoride ( $BF_3$ ) and lithium sulfite ( $Li_2SO_3$ ) produces boron sulfite ( $B_2(SO_3)_3$ ) and lithium fluoride ( $LiF$ ). The coefficient of lithium fluoride is 6, which means that 6 moles of lithium fluoride are produced for every 2 moles of boron fluoride and 3 moles of lithium sulfite that react.

Applications and Implications

The balanced chemical equation has important implications for various fields, including chemistry, materials science, and engineering. For example, the reaction between boron fluoride and lithium sulfite can be used to produce boron sulfite, which has applications in the production of ceramics, glass, and other materials. Additionally, the reaction can be used to produce lithium fluoride, which has applications in the production of batteries, fuel cells, and other energy storage devices.

Limitations and Future Work

While the balanced chemical equation provides valuable insights into the reaction between boron fluoride and lithium sulfite, there are still limitations and areas for future work. For example, the equation assumes that the reaction occurs under ideal conditions, which may not be the case in real-world applications. Additionally, the equation does not take into account the effects of temperature, pressure, and other factors that can affect the reaction. Therefore, further research is needed to fully understand the reaction and its applications.

Conclusion and Recommendations

In conclusion, the balanced chemical equation for the reaction between boron fluoride and lithium sulfite is $2BF_3 + 3Li_2SO_3 \rightarrow B_2(SO_3)_3 + 6LiF$ . The coefficient of lithium fluoride is 6, which means that 6 moles of lithium fluoride are produced for every 2 moles of boron fluoride and 3 moles of lithium sulfite that react. This equation has important implications for various fields, including chemistry, materials science, and engineering. However, further research is needed to fully understand the reaction and its applications.
