Complete Combustion
* Reactants: Propanol (C₃H₇OH) and Oxygen (O₂)
* Products: Carbon Dioxide (CO₂), Water (H₂O), and Energy (heat)
Balanced Equation:
2 C₃H₇OH + 9 O₂ → 6 CO₂ + 8 H₂O + Energy
Explanation:
* The coefficients in front of each molecule ensure that the number of atoms of each element is equal on both sides of the equation.
* Complete combustion occurs when there is enough oxygen to react with all the fuel. All the carbon atoms in propanol are oxidized to form CO₂.
Incomplete Combustion
* Reactants: Propanol (C₃H₇OH) and Oxygen (O₂)
* Products: Carbon Monoxide (CO), Carbon Dioxide (CO₂), Water (H₂O), and Energy (heat)
Balanced Equation (one possible option):
2 C₃H₇OH + 7 O₂ → 4 CO₂ + 2 CO + 8 H₂O + Energy
Explanation:
* Incomplete combustion happens when there is not enough oxygen to completely oxidize the fuel.
* This leads to the formation of carbon monoxide (CO), a toxic gas, in addition to carbon dioxide.
* The exact ratio of CO₂ to CO produced can vary depending on the oxygen availability.
Important Note: Incomplete combustion is less efficient in terms of energy released and produces harmful byproducts. It's generally undesirable, especially in enclosed spaces.
