Introduction

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 focus on balancing the chemical equation: $Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow$. We will break down the steps involved in balancing this equation and provide a clear explanation of the process.

Understanding the Chemical Equation

Before we begin balancing the equation, let's take a closer look at the reactants and products involved. The reactants are lead(III) ion ($Pb^{+3}$) and copper(II) nitrite ($Cu(NO_2)_2^{-1}$). The products are not specified, so we will need to determine them as we balance the equation.

Step 1: Write the Unbalanced Equation

The unbalanced equation is: $Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow$

Step 2: Count the Atoms

To balance the equation, we need to count the number of atoms of each element on both sides of the equation. Let's start with the reactants:

• Lead (Pb): 1 atom
• Nitrogen (N): 2 atoms
• Oxygen (O): 4 atoms
• Copper (Cu): 1 atom

Now, let's count the atoms on the product side:

• Lead (Pb): 0 atoms
• Nitrogen (N): 0 atoms
• Oxygen (O): 0 atoms
• Copper (Cu): 0 atoms

Step 3: Balance the Lead Atoms

Since there is only one lead atom on the reactant side, we need to add a coefficient in front of the lead atom to balance it. Let's add a coefficient of 1 in front of the lead atom:

$Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow Pb^{+3}$

Step 4: Balance the Nitrogen Atoms

There are 2 nitrogen atoms on the reactant side, so we need to add a coefficient of 2 in front of the nitrogen-containing compound ($NO_2$) to balance the nitrogen atoms:

$Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow Pb^{+3} + 2NO_2$

Step 5: Balance the Oxygen Atoms

There are 4 oxygen atoms on the reactant side, so we need to add a coefficient of 4 in front of the oxygen-containing compound ($NO_2$) to balance the oxygen atoms:

$Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow Pb^{+3} + 2NO_2 + 2O$

However, we can simplify this by recognizing that the oxygen atoms are already balanced. The $NO_2$ compound contains 2 oxygen atoms, and we have 2 $NO_2$ compounds, so the oxygen atoms are already balanced.

Step 6: Balance the Copper Atoms

There is only one copper atom on the reactant side, so we need to add a coefficient of 1 in front of the copper atom to balance it:

$Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow Pb^{+3} + Cu + 2NO_2$

However, we can simplify this by recognizing that the copper atom is already balanced. The $Cu(NO_2)_2^{-1}$ compound contains 1 copper atom, and we have 1 $Cu(NO_2)_2^{-1}$ compound, so the copper atom is already balanced.

Step 7: Balance the Charge

The final step is to balance the charge on both sides of the equation. The lead ion has a charge of +3, and the copper ion has a charge of +2. To balance the charge, we need to add a coefficient of 2 in front of the lead ion:

$2Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow Pb^{+3} + Cu + 2NO_2$

However, we can simplify this by recognizing that the charge is already balanced. The $Cu(NO_2)_2^{-1}$ compound has a charge of -1, and we have 2 lead ions with a charge of +3, so the charge is already balanced.

Conclusion

Balancing the chemical equation $Pb^{+3} + Cu(NO_2)_2^{-1} \rightarrow$ requires careful attention to the number of atoms of each element on both sides of the equation. By following the steps outlined in this article, we can balance the equation and determine the products involved in the reaction.
