=====================================================
Introduction
Balancing chemical equations is a crucial concept in chemistry that helps us understand the stoichiometry of chemical reactions. It involves adding coefficients to the reactants or products to ensure that the number of atoms of each element is the same on both sides of the equation. In this article, we will focus on balancing the given chemical equation and determine the correct coefficient for the product LiNO3.
The Given Unbalanced Equation
The given unbalanced equation is:
Step 1: Count the Number of Atoms of Each Element
To balance the equation, we need to count the number of atoms of each element on both sides of the equation.
- On the reactant side:
- Pb: 1
- N: 2
- O: 6
- Li: 2
- S: 1
- O: 4
- On the product side:
- Pb: 1
- S: 1
- O: 4
- Li: 1
- N: 1
- O: 3
Step 2: Identify the Imbalanced Elements
By comparing the number of atoms of each element on both sides of the equation, we can identify the imbalanced elements.
- Li: 2 (reactant side) vs 1 (product side)
- N: 2 (reactant side) vs 1 (product side)
- O: 6 (reactant side) vs 4 (product side)
Step 3: Balance the Equation
To balance the equation, we need to add coefficients in front of the reactants or products. In this case, we will add a coefficient in front of LiNO3.
- To balance Li, we need to multiply LiNO3 by 2.
- To balance N, we need to multiply LiNO3 by 2.
- To balance O, we need to multiply LiNO3 by 2.
Step 4: Write the Balanced Equation
After adding the coefficients, the balanced equation becomes:
Conclusion
In conclusion, the correct coefficient that should appear in front of LiNO3 in the balanced equation is 2.
Final Answer
The final answer is 2.

Introduction
Balancing chemical equations is a crucial concept in chemistry that helps us understand the stoichiometry of chemical reactions. In our previous article, we walked through the steps to balance a given chemical equation and determined the correct coefficient for the product LiNO3. In this article, we will address some common questions and concerns related to balancing chemical equations.
Q&A
Q: What is the purpose of balancing chemical equations?
A: The purpose of balancing chemical equations is to ensure that the number of atoms of each element is the same on both sides of the equation. This helps us understand the stoichiometry of chemical reactions and predict the amounts of reactants and products involved.
Q: How do I know which elements are imbalanced in a chemical equation?
A: To identify the imbalanced elements, count the number of atoms of each element on both sides of the equation. Compare the counts to determine which elements are imbalanced.
Q: What are the steps to balance a chemical equation?
A: The steps to balance a chemical equation are:
- Count the number of atoms of each element on both sides of the equation.
- Identify the imbalanced elements.
- Add coefficients in front of the reactants or products to balance the equation.
Q: How do I choose which reactant or product to add a coefficient to?
A: To choose which reactant or product to add a coefficient to, start with the element that appears only once on the reactant side. Add a coefficient in front of the reactant or product that contains this element.
Q: What if I have multiple imbalanced elements?
A: If you have multiple imbalanced elements, balance one element at a time. Start with the element that appears only once on the reactant side and add a coefficient in front of the reactant or product that contains this element.
Q: Can I add coefficients to both sides of the equation?
A: Yes, you can add coefficients to both sides of the equation. However, be careful not to add coefficients that would change the identity of the reactants or products.
Q: How do I know if I have balanced the equation correctly?
A: To check if you have balanced the equation correctly, count the number of atoms of each element on both sides of the equation. If the counts are the same, you have balanced the equation correctly.
Q: What if I get stuck balancing a chemical equation?
A: If you get stuck balancing a chemical equation, try breaking it down into smaller steps. Focus on one element at a time and add coefficients in front of the reactants or products that contain this element.
