What harm does the presence of carbon monoxide ( CO) in the air do to animals ?
by

1 Answer

Answer :

Carbon monoxide ( CO) is a highly toxic gas , which reacts with hemoglobin in the blood to form carboxy hemoglobin compounds and reduces the level of oxygen transport in the body. Excessive presence of this gas can lead to death.

Isn't carbon monoxide heavier than air? If so shouldn't CO detectors be put at floor level?

Description : Isn't carbon monoxide heavier than air? If so shouldn't CO detectors be put at floor level?

Last Answer : molecular weight of CO ~ 28 (12+16), while the main ingredients of air are O2 = 32 (2 16) and N2 = 28; mixed together, that's heavier than CO. Alone from that, I'd say CO is lighter. Of course ... right says lighter than air . So CO rises. Therefore, again, keep your head down in case of smoke ;-)!
