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

Introduction

Balancing chemical equations is a crucial step in chemistry that helps us understand the stoichiometry of chemical reactions. It is essential to balance chemical equations to ensure that the law of conservation of mass is obeyed, which states that matter cannot be created or destroyed in a chemical reaction. In this article, we will focus on balancing the chemical equation: ${ \ldots , Cr \left( NO_2 \right)_2 + \ldots , \left( NH_4 \right)_2 SO_4 \rightarrow \ldots , CrSO_4 + \ldots , NH_4 NO_2 }$

Understanding the Chemical Equation

The given chemical equation is: ${ \ldots , Cr \left( NO_2 \right)_2 + \ldots , \left( NH_4 \right)_2 SO_4 \rightarrow \ldots , CrSO_4 + \ldots , NH_4 NO_2 }$

To balance this equation, we need to identify the reactants and products. The reactants are ${ Cr \left( NO_2 \right)_2 , \text{and} , \left( NH_4 \right)_2 SO_4 }$

The products are ${ CrSO_4 , \text{and} , NH_4 NO_2 }$

Step 1: Count the Atoms

The first step in balancing a chemical equation is to count the atoms of each element on both the reactant and product sides. This will help us identify which elements are imbalanced.

Element	Reactant Side	Product Side
Cr	1	1
N	2	2
O	4	4
H	8	8
S	1	1

Step 2: Balance the Elements

Based on the count of atoms, we can see that the elements Cr, N, O, H, and S are balanced. However, we need to balance the elements Cr and S, which are not balanced.

To balance the element Cr, we need to add a coefficient of 2 in front of Cr on the reactant side.

To balance the element S, we need to add a coefficient of 2 in front of SO4 on the reactant side.

Step 3: Balance the Coefficients

After balancing the elements, we need to balance the coefficients. The balanced equation is:

{ 2 \, Cr \left( NO_2 \right)_2 + \left( NH_4 \right)_2 SO_4 \rightarrow CrSO_4 + NH_4 NO_2 \}

Step 4: Check the Balancing

To ensure that the equation is balanced, we need to check the count of atoms on both the reactant and product sides.

Element	Reactant Side	Product Side
Cr	2	1
N	4	2
O	8	4
H	8	8
S	2	1

The equation is balanced, and the count of atoms on both the reactant and product sides is the same.

Conclusion

Balancing chemical equations is a crucial step in chemistry that helps us understand the stoichiometry of chemical reactions. In this article, we balanced the chemical equation: ${ \ldots , Cr \left( NO_2 \right)_2 + \ldots , \left( NH_4 \right)_2 SO_4 \rightarrow \ldots , CrSO_4 + \ldots , NH_4 NO_2 }$

We identified the reactants and products, counted the atoms, balanced the elements, and balanced the coefficients. The balanced equation is:

{ 2 \, Cr \left( NO_2 \right)_2 + \left( NH_4 \right)_2 SO_4 \rightarrow CrSO_4 + NH_4 NO_2 \}
