During inhaling, you take in fresh air from the environment, which contains a higher concentration of oxygen. When you exhale, your body has used some of that oxygen for cellular respiration, converting it into carbon dioxide in the process. This is why exhaled air has a lower oxygen content than inhaled air.
What else can I help you with?
Does nitrates or nitrites contain more oxygen atoms?
A nitrate is represented by -NO3 whereas a nitrite is represented by -NO2. So to answer your question, nitrates have 1 oxygen atom more than nitrites.
Does cold air contain more oxygen than warm air?
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Does hydrogen contain one more oxygen than water or two more?
Hydrogen contains no oxygen in its chemical structure. Water contains two hydrogen atoms and one oxygen atom.
Why HNO3 is stronger than HNO2?
HNO3 is stronger than HNO2 because it has one more oxygen atom, making it a stronger acid. The presence of more oxygen atoms leads to greater electronegativity and more stability in the resulting conjugate base after donating a proton, resulting in increased acidity.
Do veins contain more oxygen or carbon dioxide?
Veins carry blood low in oxygen back to the heart. However, the amount of oxygen in veins is still higher than the amount of carbon dioxide.
Does the brain use more than one quarter of the oxygen breathed by the human body?
Less than one quarter, about 20 %.
Is hydrogen more than oxygen in universe?
Yes, there is more Hydrogen than anything else in the universe. Most molecules which contain Oxygen also contain Hydrogen, and there is usually more Hydrogen than Oxygen within the molecule already, for example Water, H2O (There are exceptions, such as Oxygen, O2 and Ozone, O3)
What do lipids have more of than oxygen?
Lipids also contain carbon and hydrogen.
Does nitrates or nitrites contain more oxygen atoms?
A nitrate is represented by -NO3 whereas a nitrite is represented by -NO2. So to answer your question, nitrates have 1 oxygen atom more than nitrites.
At the peak of the inspiratory phase the alveoli contain how much of oxygen and carbon dioxide?
More oxygen than carbon dioxide.
Does cold air contain more oxygen than warm air?
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Does CO contain polar covalent bond?
Yes it does, with partial negative charges on oxygen, as oxygen is more electronegative than carbon.
Does hydrogen contain one more oxygen than water or two more?
Hydrogen contains no oxygen in its chemical structure. Water contains two hydrogen atoms and one oxygen atom.
Does a lake containing only catfish contain more oxygen than lake with trout only?
not usually
Does a lake or a river contain more dissolved oxygen?
the river would contain more dissolved oxygen because the water movements cause more oxygen to be produced...try looking at lab bench..it's like a prelab but it helps with the basic information
What is a gas that you breathe out?
Carbon dioxide Nitrogen Water vapor (and believe it or not you also breath out Oxygen - although less than you breathed in).
Why HNO3 is stronger than HNO2?
HNO3 is stronger than HNO2 because it has one more oxygen atom, making it a stronger acid. The presence of more oxygen atoms leads to greater electronegativity and more stability in the resulting conjugate base after donating a proton, resulting in increased acidity.
