Study Notes
Combustion Defined
- Combustion is a rapid chemical reaction between a fuel and oxygen, producing oxides and energy.
Types of Combustion
-
Complete Combustion:
- Requires a plentiful oxygen supply.
- Fuel is entirely consumed.
- Produces carbon dioxide, water, and energy.
- General formula: Hydrocarbon (CxHy) + Oxygen (O2) → Carbon Dioxide (CO2) + Water (H₂O) + Energy
-
Incomplete Combustion:
- Occurs when oxygen supply is limited.
- Fuel is not entirely consumed.
- Produces carbon monoxide, carbon, carbon dioxide, water, and energy.
- Often indicated by an orange flickering flame.
- Visible soot is a sign of incomplete combustion.
Incomplete Combustion Dangers
-
Carbon Monoxide Poisoning:
- A highly toxic, odourless, and colourless gas.
- Can cause symptoms like headaches, dizziness, nausea, and respiratory problems.
- Often a product of incomplete combustion in confined spaces (e.g., running a car engine in a closed garage).
Common Hydrocarbons
- List of common hydrocarbons is not provided in the text.
