=====================================================
Balancing chemical equations is a crucial concept in chemistry that helps us understand the stoichiometry of chemical reactions. It involves adding coefficients in front of the formulas of reactants or products to ensure that the number of atoms for each element is the same on both the reactant and product sides of the equation. In this article, we will explore how to balance chemical equations, using the given formula equation as an example.
Understanding the Given Equation
The given equation is:
This equation represents a reaction between lead(II) nitrate and lithium sulfate to form lead(II) sulfate and lithium nitrate.
Identifying the Imbalance
To balance the equation, we need to identify the elements that are not balanced. Let's start by counting the number of atoms for each element on both sides of the equation.
Reactant Side
- Lead (Pb): 1
- Nitrogen (N): 2
- Oxygen (O): 6
- Lithium (Li): 2
- Sulfur (S): 1
Product Side
- Lead (Pb): 1
- Sulfur (S): 1
- Nitrogen (N): 1
- Oxygen (O): 4
- Lithium (Li): 1
As we can see, the number of atoms for each element is not the same on both sides of the equation. The elements that are not balanced are nitrogen, oxygen, and lithium.
Balancing the Equation
To balance the equation, we need to add coefficients in front of the formulas of reactants or products. Let's start by balancing the nitrogen and oxygen atoms.
Balancing Nitrogen and Oxygen
Since there are 2 nitrogen atoms on the reactant side, we need to add a coefficient of 2 in front of the formula of lithium nitrate on the product side.
However, this would leave us with 12 oxygen atoms on the product side, while there are only 6 oxygen atoms on the reactant side. To balance the oxygen atoms, we need to add a coefficient of 2 in front of the formula of lead(II) nitrate on the reactant side.
Balancing Lithium
Now that we have balanced the nitrogen and oxygen atoms, we can focus on balancing the lithium atoms. Since there are 2 lithium atoms on the reactant side, we need to add a coefficient of 2 in front of the formula of lithium nitrate on the product side.
However, this would leave us with 2 lithium atoms on the product side, while there are only 2 lithium atoms on the reactant side. To balance the lithium atoms, we need to add a coefficient of 2 in front of the formula of lithium sulfate on the reactant side.
Final Balanced Equation
After adding the necessary coefficients, we get the final balanced equation:
