Let's classify each of the given reactions based on their types:
1. **2H₂O → 2H₂ + O₂**
- **Type:** b. Decomposition
- Explanation: Water is broken down into hydrogen and oxygen.
2. **2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O**
- **Type:** c. Combustion
- Explanation: Ethane (C₂H₆) is combusted in the presence of oxygen to produce carbon dioxide and water.
3. **2 Na + Cl₂ → 2 NaCl**
- **Type:** e. Synthesis
- Explanation: Sodium and chlorine react to form sodium chloride.
4. **4 AlBr₃ + 3O₂ → 2 Al₂O₃ + 6 Br₂**
- **Type:** a. Double Replacement
- Explanation: While the reaction doesn't precisely fit typical definitions (like ionic exchange), it features both aluminum and bromine transitioning to different states/products, which can be interpreted by some as a double replacement. However, this classification may vary; the main reaction involves species converting forms.
5. **KCl + NaI → KI + NaCl**
- **Type:** a. Double Replacement
- Explanation: Potassium chloride and sodium iodide exchange partners to form potassium iodide and sodium chloride.
Now let's summarize the classifications:
1. **Decomposition:** 2H₂O → 2H₂ + O₂
2. **Combustion:** 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
3. **Synthesis:** 2 Na + Cl₂ → 2 NaCl
4. **Double Replacement:** 4 AlBr₃ + 3O₂ → 2 Al₂O₃ + 6 Br₂ (can also be debated)
5. **Double Replacement:** KCl + NaI → KI + NaCl
1. **2H₂O → 2H₂ + O₂**
- **Type:** b. Decomposition
- Explanation: Water is broken down into hydrogen and oxygen.
2. **2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O**
