Balancing chemical equations is a crucial step in understanding chemical reactions and stoichiometry. It involves adding coefficients to the reactants and 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 balance three chemical equations and provide a step-by-step guide on how to do it.
Equation 1: Nitric Acid Decomposition
The first equation involves the decomposition of nitric acid (HNO3) into nitrogen (N2), nitrogen dioxide (NO2), and oxygen (O2).
\text{HNO}_3 \rightarrow \text{N}_2 + \text{NO}_2 + \text{O}_2
To balance this equation, we need to add coefficients to the reactants and products. Let's start by counting the number of atoms of each element on both sides of the equation.
| Element | Reactants | Products |
|---|---|---|
| H | 1 | 0 |
| N | 1 | 2 |
| O | 3 | 5 |
As we can see, the number of atoms of each element is not the same on both sides of the equation. To balance the equation, we need to add coefficients to the reactants and products.
2\text{HNO}_3 \rightarrow \text{N}_2 + 2\text{NO}_2 + \text{O}_2
However, this is not balanced yet. Let's count the number of atoms of each element again.
| Element | Reactants | Products |
|---|---|---|
| H | 2 | 0 |
| N | 2 | 3 |
| O | 6 | 5 |
We still have an imbalance in the number of oxygen atoms. To balance the equation, we need to add another oxygen atom to the products.
2\text{HNO}_3 \rightarrow \text{N}_2 + 2\text{NO}_2 + \frac{3}{2}\text{O}_2
However, we cannot have a fraction as a coefficient. To fix this, we can multiply the entire equation by 2.
4\text{HNO}_3 \rightarrow 2\text{N}_2 + 4\text{NO}_2 + 3\text{O}_2
This is the balanced equation for the decomposition of nitric acid.
Equation 2: Copper Sulfate and Iron Reaction
The second equation involves the reaction between copper sulfate (CuSO4) and iron (Fe) to form iron sulfate (FeSO4) and copper (Cu).
\text{CuSO}_4 + \text{Fe} \rightarrow \text{FeSO}_4 + \text{Cu}
To balance this equation, we need to add coefficients to the reactants and products. Let's start by counting the number of atoms of each element on both sides of the equation.
| Element | Reactants | Products |
|---|---|---|
| Cu | 1 | 1 |
| S | 1 | 1 |
| O | 4 | 4 |
| Fe | 1 | 1 |
As we can see, the number of atoms of each element is the same on both sides of the equation. This means that the equation is already balanced.
Equation 3: Acetic Acid Decomposition
The third equation involves the decomposition of acetic acid (CH3COOH) into carbon dioxide (CO2) and water (H2O).
\text{CH}_3\text{COOH} \rightarrow \text{CO}_2 + \text{H}_2\text{O}
To balance this equation, we need to add coefficients to the reactants and products. Let's start by counting the number of atoms of each element on both sides of the equation.
| Element | Reactants | Products |
|---|---|---|
| C | 1 | 1 |
| H | 4 | 2 |
| O | 2 | 3 |
As we can see, the number of atoms of each element is not the same on both sides of the equation. To balance the equation, we need to add coefficients to the reactants and products.
2\text{CH}_3\text{COOH} \rightarrow 2\text{CO}_2 + 2\text{H}_2\text{O}
However, this is not balanced yet. Let's count the number of atoms of each element again.
| Element | Reactants | Products |
|---|---|---|
| C | 2 | 2 |
| H | 8 | 4 |
| O | 4 | 6 |
We still have an imbalance in the number of hydrogen atoms. To balance the equation, we need to add another hydrogen atom to the reactants.
2\text{CH}_3\text{COOH} \rightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}
However, we still have an imbalance in the number of oxygen atoms. To balance the equation, we need to add another oxygen atom to the reactants.
2\text{CH}_3\text{COOH} + \text{H}_2\text{O} \rightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}
However, this is not balanced yet. Let's count the number of atoms of each element again.
| Element | Reactants | Products |
|---|---|---|
| C | 2 | 2 |
| H | 8 | 8 |
| O | 5 | 8 |
We still have an imbalance in the number of oxygen atoms. To balance the equation, we need to add another oxygen atom to the reactants.
2\text{CH}_3\text{COOH} + \frac{3}{2}\text{H}_2\text{O} \rightarrow 2\text{CO}_2 + 3\text{H}_2\text{O}
However, we cannot have a fraction as a coefficient. To fix this, we can multiply the entire equation by 2.
4\text{CH}_3\text{COOH} + 3\text{H}_2\text{O} \rightarrow 4\text{CO}_2 + 6\text{H}_2\text{O}
This is the balanced equation for the decomposition of acetic acid.
