![**Balancing Redox Reactions: A Step-by-Step Guide**
Please show step by step how to balance the following redox equation:
\[ \text{Mn(NO}_3\text{)}_2 + \text{NaBiO}_3 + \text{HNO}_3 \rightarrow \text{HMnO}_4 + \text{Bi(NO}_3\text{)}_3 + \text{NaNO}_3 + \text{H}_2\text{O} \]
**Steps to Balance:**
1. **Assign Oxidation Numbers:**
- Determine the oxidation states of each element in the reactants and products.
2. **Identify Oxidation and Reduction:**
- Find which elements undergo changes in oxidation states.
3. **Write Half-Reactions:**
- Separate the oxidation and reduction processes into two half-reactions.
4. **Balance Atoms in Each Half-Reaction:**
- Balance atoms other than O and H first, then balance oxygen using \(\text{H}_2\text{O}\) and hydrogen using \(\text{H}^+\).
5. **Balance Charges:**
- Add electrons to balance the charges in each half-reaction.
6. **Equalize Electron Transfer:**
- Multiply each half-reaction by the appropriate coefficients to equalize the number of electrons transferred.
7. **Combine Half-Reactions:**
- Add the balanced half-reactions, canceling out electrons.
8. **Verify Mass and Charge Balance:**
- Ensure all atoms and charges are balanced in the final equation.
This process will yield the balanced redox equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18d18743-0691-4c02-8821-e1dee8aae4f7%2Fe28ec29f-6e72-47c9-a3c7-b68f31d0959e%2Fpqoqk4h_processed.png&w=3840&q=75)
