![## Oxidation Number Method in Redox Reactions
**Problem Statement:**
8. Assign oxidation numbers, find the reductant and oxidant atoms, and relate them before and after the reaction. Then, balance using the oxidation number method.
**Chemical Equation:**
\[ \_\_ \text{ClF}_3(g) + \_\_ \text{N}_2\text{H}_4(g) \rightarrow \_\_ \text{NF}_3(g) + \_\_ \text{HCl}(g) + \_\_ \text{HF}(g) \]
- **Reductant atom:** _____
- **Oxidant atom:** _____
**Instructions:**
1. **Assign Oxidation Numbers:**
- Determine the oxidation number of each element in the reactants and products.
2. **Identify Reductant and Oxidant Atoms:**
- The reductant is the atom that loses electrons (oxidation).
- The oxidant is the atom that gains electrons (reduction).
3. **Balance the Reaction:**
- Use the changes in oxidation numbers to balance the overall chemical equation.
**Note:** This exercise helps in understanding electron transfer processes in redox reactions and mastering the technique of balancing complex reactions systematically.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7e6fe4d9-c522-461f-bc62-94d23fd62501%2F5f099b97-43f6-4c1b-9d34-80bad3f1931a%2F4dtmsvp_processed.png&w=3840&q=75)
