Question
### Balancing Chemical Equations

**Problem Statement:**

Balance the following chemical equation:

\[ \text{PbN}_6 + \text{CrMn}_2\text{O}_8 \rightarrow \text{Pb}_3\text{O}_4 + \text{Cr}_2\text{O}_3 + \text{MnO}_2 + \text{NO} \]

**Question:**

Assume the coefficient of NO is 90. What is the balanced equation?

**Solution:**
- The reactants and products are represented with boxes to insert the correct stoichiometric coefficients.
- The balanced equation will ensure that the number of atoms of each element is the same on both sides of the equation.

\[
\Box \text{PbN}_6 + \Box \text{CrMn}_2\text{O}_8 \rightarrow \Box \text{Pb}_3\text{O}_4 + \Box \text{Cr}_2\text{O}_3 + \Box \text{MnO}_2 + \Box \text{NO}
\]

Steps to achieve balance involve:
- Matching numbers of Pb, Cr, Mn, N, and O on both sides.
- Adjusting coefficients to satisfy conservation of mass.

**Answering the Query:**

When the coefficient of NO is set to 90, use algebraic methods or systematic trial/error to determine the coefficients of the other compounds while ensuring equal atom counts across the equation.
