because it doesn't have hydrogen in it. we should only breathe in H2O, in air form.
When it has no other gasses mixed with it. For example, we breathe oxygen, but we do not breathe pure oxygen because it is mixed with nitrogen.
Pure oxygen is very harmful to humans at pressures higher than ground level, with the effects becoming worse the higher the pressure - ie. when scuba diving. At lower pressures, such as the cockpit of a plane at altitude, pure oxygen becomes much safer to breathe, to the point some astronauts have breathed it for around 2 weeks (at low pressure) with no detrimental effects.
Pure oxygen is used in oxygen tents to increase the concentration of oxygen in the air that the patient breathes. This higher concentration of oxygen can help improve oxygen delivery to tissues, supporting the body's healing processes. It can be particularly beneficial for patients with respiratory conditions or those experiencing low oxygen levels.
when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide
The air you breathe out contains less oxygen because your body extracts oxygen from the air when you breathe in and uses it during cellular respiration to produce energy. As a result, the air you breathe out has a higher concentration of carbon dioxide and less oxygen.
It is useful because we can breathe it.
No, oxygen tanks typically contain compressed or liquid oxygen that is a higher concentration than the ambient air we breathe (which is about 21% oxygen). However, it is not 100% pure oxygen as that can be harmful and pose a fire hazard.
No. It is only about 21% oxygen. Air is about 78% nitrogen.
Humans cannot breathe a combination of pure oxygen and hydrogen. Oxygen is necessary for respiration, but hydrogen is highly flammable and not suitable for breathing. Mixing the two gases is dangerous and can create a potential explosion hazard.
When it has no other gasses mixed with it. For example, we breathe oxygen, but we do not breathe pure oxygen because it is mixed with nitrogen.
Yes, but in the form of carbon dioxide, with contains two atoms of oxygen and one of carbon. Cows don't breathe out the pure form of oxygen; they breathe in oxygen as well as nitrogen from the atmosphere.
somr people may say not much but that's a lie hospital use pure oxygen for life support you can breathe in pure oxygen for 12 years strait and not die
Pure oxygen can be harmful when inhaled at high concentrations because it can lead to oxygen toxicity. Oxygen toxicity can cause lung damage, seizures, and other serious health problems. It is important to use oxygen as directed by a healthcare professional to avoid these potential risks.
Because too much oxygen is harmful to the environment.
Pure oxygen is very harmful to humans at pressures higher than ground level, with the effects becoming worse the higher the pressure - ie. when scuba diving. At lower pressures, such as the cockpit of a plane at altitude, pure oxygen becomes much safer to breathe, to the point some astronauts have breathed it for around 2 weeks (at low pressure) with no detrimental effects.
There is high concentrated oxygen treatments, or there is the standard oxygen treatments. The high concentrated is almost pure oxygen, people like doctors and scuba divers breathe pure oxygen almost every day.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
