Questions and Answers List
level questions: Complete and incomplete combustion
Question
Answer
The chemical process of burning.
Combustion.
What is the chemical term for burning?
Combustion.
Compounds made up of hydrogen and carbon atoms.
Hydrocarbons
What are hydrocarbons?
Compounds made up of hydrogen and carbon atoms.
The release of energy during a chemical reaction, such as combustion.
Energy Release (Exothermic)
What happens when hydrocarbons combust?
Energy is released.
Combustion that occurs when there is plenty of oxygen present.
Complete Combustion
What are the products of complete combustion?
Carbon dioxide (CO2) and water (H2O).
Substances formed as a result of a combustion reaction.
Products of Combustion
In the case of complete combustion, what are the products of combustion?
Carbon dioxide and water.
A gas that is necessary for combustion to occur.
Oxygen
What is necessary for complete combustion to occur?
Plenty of oxygen.
Combustion that occurs when there is insufficient oxygen for the process to be completed.
Incomplete Combustion
What happens if there's not enough oxygen for complete combustion?
Incomplete combustion occurs.
Substances formed as a result of incomplete combustion, including carbon (soot) and carbon monoxide.
Products of Incomplete Combustion
What are the products of incomplete combustion?
Carbon (soot), carbon monoxide, carbon dioxide, and water.
A colorless, odorless, and poisonous gas produced during incomplete combustion.
Carbon Monoxide.
What is one of the products of incomplete combustion and is also poisonous?
Carbon Monoxide.
A black, powdery substance consisting of carbon, formed during incomplete combustion.
Soot.
What is produced as a result of incomplete combustion and appears as a black powdery substance?
Soot.
The condition that leads to incomplete combustion due to a lack of oxygen.
Insufficient Oxygen.
What condition leads to incomplete combustion?
Insufficient Oxygen.
Dangers associated with inhaling carbon monoxide, including poisoning.
Hazards of Carbon Monoxide
Why is carbon monoxide hazardous?
It is poisonous and can cause poisoning when inhaled.
A toxic gas produced during incomplete combustion that binds with haemoglobin (in red blood cells) and reduces the oxygen-carrying capacity of red blood cells.
Carbon Monoxide.
What is the primary toxic gas produced during incomplete combustion?
Carbon Monoxide.
Dangers associated with inhaling carbon monoxide, including its impact on oxygen transport in the blood.
Health Hazards of Carbon Monoxide
How does carbon monoxide affect the human body?
It binds with haemoglobin, reducing the oxygen-carrying capacity of red blood cells.
Tiny particles of carbon produced during incomplete combustion, causing environmental issues and health problems.
Soot.
What is the name for the tiny particles of carbon produced as a result of incomplete combustion?
Soot.
The effects of soot on the environment, including blackening of trees and buildings and reducing light penetration.
Environmental Impact of Soot
How does soot impact the environment?
It blackens trees and buildings, limiting light penetration
Difficulties in detecting carbon monoxide due to its colorless and odorless nature.
Detection Challenges
Why is carbon monoxide challenging to detect?
It is colorless and odorless.
Potential outcomes of inhaling carbon monoxide, including loss of consciousness or death.
Consequences of Breathing Carbon Monoxide
What can happen to individuals who breathe in carbon monoxide?
They may lose consciousness or die.
