CO displaces oxygen in the blood stream and once it bonds with the blood cells, it is hard to dislodge. A person with an overdose of CO will die sometimes even if they are given pure oxygen because the pure oxygen has nothing to bond to and be carried to the body cells. The blood cells accept CO more readily than oxygen and hang on to it longer.

CO2 is also dangerous, but in a different way. CO2 does not react with the body as does CO, but if the concentration of CO2 is too high, then that means that not enough oxygen is available. This can also kill you -- but the effect is more like holding your breath than breathing a toxic chemical. Too much CO2 isn't bad by itself, it's just that it usually goes along with not enough O2, which is bad. This commonly affects underwater swimmers for instance who build up too much CO2 in their bloodstream as they swim underwater, causing them to pass out under water and drown. You should NEVER hyperventilate before swimming a long distance under water -- my father nearly drowned this way!

Which is dangerous to breathe carbon dioxide or carbon monoxide?

Both can be dangerous. CO2 from the side of if there is only co2 there is no oxygen. However, Carbon monoxide can bind 10 times stronger to the iron centre in haemoglobin than oxygen does, therefore you cannot transport oxygen around your body. I'd say due to this, CO is likely to be far more dangerous


How burning carbon in air can lead o the formation of carbon monoxide?

The formation of carbon dioxide. Burning coal that releases only carbon dioxide means the coal is completely burnt and more energy is produced. Carbon monoxide is released when the combustion process is incomplete.


What do you get when you mix one carbon atom with two oxygen atoms?

What you mean is "What is the product of a reaction in which one carbon atom bonds to one oxygen atom?" The answer is carbon monoxide, or CO, which is extremely dangerous in large quantities. It is one of the by-products of incomplete combustion along with carbon dioxide (CO2), carbon (C) and water (H2O). When you breath in carbon monoxide, it attaches to your red blood cells and does not allow them to pick up oxygen.

Why there is increase in carbon dioxide gas?

More living things such as humans are being brought into existence, breathing out more carbon dioxide. Factories, cars and planes also contribute to rising carbon dioxide and carbon monoxide in the atmosphere from the smoke they release. Plants such as trees are supposed to convert the carbon dioxide into oxygen, but we keep cutting them down. In short - because of the human race.

Why is carbon monoxide more dangerous than carbon dioxide?

Carbon monoxide bonds the the hemoglobin in out red blood cells. This renders our blood unable to transport oxygen. Carbon dioxide does not do this.


Is Carbon Monoxide or Sulfur Dioxide more deadly?

carbon monoxide


Is there more carbon in carbon dioxide or carbon monoxide?

There is proportionally more carbon in carbon monoxide than there is in carbon dioxide. Carbon monoxide, CO, has a one-to-one ration of carbon to oxygen. Carbon dioxide, CO2, has a one-to-two ration of carbon to oxygen.


How do carbon monoxide and carbon dioxide differ?

Carbon dioxide is Co2, while carbon monoxide is minus a oxygen atom and is CO. Carbon monoxide is also ten times more toxic than carbon dioxide.


Why do old cars give more carbon monoxide?

Old cars give off more carbon dioxide because they do not have catalytic converters. Catalytic converters act as catalysts, converting dangerous substances such carbon monoxide into harmless compounds.

Why is carbon dioxide from your body?

Carbon Dioxide is toxic in large concentrations. Mild symptoms include nausea and muscle cramp, but carbon dioxide poisoning can be fatal in extreme cases.Not to be confused with carbon monoxide poisoning, which is harder to detect and a lot more dangerous.
