Complete and Incomplete Combustion

What is the difference between complete and incomplete combustion?

• Complete combustion releases harmful pollutants into the environment, while incomplete combustion does not
• Complete combustion produces carbon monoxide, while incomplete combustion produces carbon dioxide
• Complete combustion occurs when there is insufficient oxygen available, while incomplete combustion occurs when there is plentiful oxygen available
• Complete combustion occurs when a fuel combines with oxygen in plentiful supply, while incomplete combustion occurs when there is insufficient oxygen available

What is the general equation for complete combustion?

• Fuel + Oxygen (limited supply) → Carbon dioxide + Water + Heat energy
• Fuel + Oxygen (limited supply) → Carbon monoxide + Carbon/soot + Water + Heat energy
• Fuel + Oxygen → Carbon dioxide + Water + Heat energy
• Fuel + Oxygen → Carbon monoxide + Carbon/soot + Water + Heat energy

What is the balanced equation for the incomplete combustion of propane?

• C3H8 + 4O2 → 3CO2 + 4H2O + Heat energy
• C3H8 + 5O2 → 3CO2 + 4H2O + Heat energy
• C3H8 + 2O2 → 3CO + 4H2O + Heat energy
• C3H8 + 3O2 → 3CO2 + 4H2O + Heat energy

What is the balanced equation for the complete combustion of methane?

• CH4 + 4O2 → CO2 + 2H2O
• CH4 + O2 → CO2 + H2O
• CH4 + 3O2 → CO2 + 2H2O
• CH4 + 2O2 → CO2 + 2H2O

What is combustion?

• The process of a material reacting with water to produce heat and light
• The process of a material reacting with carbon dioxide to produce heat and light
• The process of a material reacting with oxygen to produce heat and light
• The process of a material reacting with nitrogen to produce heat and light

What is the second step in balancing combustion equations?
