Here are 5 examples of combustion reactions along with their balanced equations:
1. **Combustion of Methane (CH₄)**
- **Balanced Equation:** CH₄ + 2O₂ → CO₂ + 2H₂O
- In this reaction, methane (CH₄) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O) as products. This is a common example of combustion as it involves the reaction of a hydrocarbon with oxygen to produce carbon dioxide and water.
2. **Combustion of Ethanol (C₂H₅OH)**
- **Balanced Equation:** C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
- Ethanol (C₂H₅OH) undergoes combustion with oxygen to produce carbon dioxide (CO₂) and water (H₂O) as the combustion products. This reaction is often used in alcohol-based fuels.
3. **Combustion of Propane (C₃H₈)**
- **Balanced Equation:** C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
- Propane (C₃H₈) undergoes combustion with oxygen to produce carbon dioxide (CO₂) and water (H₂O) as the products. Propane is commonly used as a fuel for heating and cooking.
4. **Combustion of Octane (C₈H₁₈)**
- **Balanced Equation:** C₈H₁₈ + 12.5O₂ → 8CO₂ + 9H₂O
- Octane (C₈H₁₈), a component of gasoline, undergoes combustion with oxygen to produce carbon dioxide (CO₂) and water (H₂O) as the products. This reaction is responsible for the energy release in internal combustion engines.
5. **Combustion of Sulfur (S₈)**
- **Balanced Equation:** S₈ + 8O₂ → 8SO₂
- Sulfur (S₈) undergoes combustion with oxygen to produce sulfur dioxide (SO₂) as the product. This reaction is important in industrial processes and environmental chemistry.
These examples illustrate the process of combustion, where a fuel reacts with oxygen to produce heat, light, and combustion products such as carbon dioxide and water.
