Carbon Monoxide and Particulates | GCSE Chemistry

Incomplete combustion releases toxic carbon monoxide and microscopic soot particles.

Why is carbon monoxide called a silent killer?

What is Carbon Monoxide and Particulates | GCSE Chemistry?

"Harmful products of incomplete combustion including a toxic gas and solid carbon particles."

Question 1

The greenhouse effect works by trapping which type of radiation?

Question 2

Which of these is a 'direct' way to reduce your personal carbon footprint?

Question 3

Which process significantly reduced CO2 levels in the early atmosphere?

Question 4

What was the main gas in Earth's early atmosphere?

Toxic Incomplete

Incomplete combustion: Occurs when oxygen is limited.

Carbon Monoxide (CO): Colorless, odorless toxic gas that binds to haemoglobin.

Particulates (Soot): Small carbon particles that cause global dimming and lung damage.

Produced in car engines and poorly ventilated fires.

Exam Tip

Safety Check: Always have a CO alarm in rooms with fuel-burning appliances.
