🌍 CARBON DIOXIDE vs CARBON MONOXIDE

What is carbon dioxide?

CO₂, a carbon oxide formed during complete combustion when there is plenty of oxygen.

What is carbon monoxide?

CO, a carbon oxide formed during incomplete combustion when there is not enough oxygen.

What is complete combustion?

Combustion that occurs when there is a sufficient/plentiful supply of oxygen, producing carbon dioxide from carbon-containing fuels.

What is incomplete combustion?

Combustion that occurs when there is a limited supply of oxygen, which can produce carbon monoxide.

What is the equation for complete combustion of carbon?

C + O₂ → CO₂

What is the equation for incomplete combustion of carbon?

2C + O₂ → 2CO

Which carbon oxide is associated with complete combustion?

Carbon dioxide (CO₂).

Which carbon oxide is associated with incomplete combustion?

Carbon monoxide (CO).

Which carbon oxide is essential for photosynthesis?

Carbon dioxide (CO₂).

What do plants use carbon dioxide for?

Plants absorb carbon dioxide during photosynthesis to make glucose and release oxygen.

Is carbon dioxide always harmful?

No. Carbon dioxide is essential for photosynthesis and is naturally present in Earth's atmosphere. However, very high concentrations can be dangerous.

What is the main danger of carbon monoxide?

Carbon monoxide is highly toxic and interferes with the blood's ability to transport oxygen.

Why is carbon monoxide called a "silent killer"?

Because it is colourless, odourless and tasteless, so it cannot be detected by our senses.

Which is more toxic: CO₂ or CO?

Carbon monoxide (CO) is highly toxic.

What is one danger of very high carbon dioxide concentrations?

CO₂ can displace oxygen, potentially causing asphyxiation in a confined space.

What is the molecular structure of carbon dioxide?

O=C=O

What is the molecular structure of carbon monoxide?

C≡O
