Why is a burning charcoal stove in a poorly ventilated room likely to cause death of the inhabitants?

Answer:

-Burning charcoal in limited supply of air produces carbon (II) oxide which accumulates to high levels in a room.
-Haemoglobin has a higher affinity for carbon (II) oxide, they combine to form carboxyhaemoglobin which does not easily dissociate.
-This reduces the capacity of haemoglobin to carry oxygen, thereby causing suffocation.
-It is respiratory poisonous if breathes for long.
