What is the atomicity of oxygen in oxygen molecule?
Two or diatomic in O2 molecule.
How would you describe the electron geometry around oxygen in water?
The water molecule has a 4 electron group, as the oxygen has two lone pairs. The two lone pairs are going to repulse the hydrogen atoms creating a bent shape for the water molecule.
How many atoms does oxygen have in the molecule?
One molecule of Oxygen contains two atoms.
How many atoms are there in an oxygen molecule O(2)?
ONE oxygen molecule (O2) contains two atoms of oxygen (O).
Does an oxygen molecule usually have two oxygen atoms?
Yes, oxygen is a diatomic molecule, meaning it naturally forms O2.
Trace a molecule of oxygen from the air until it reaches the blood?
External Nares (Nostrils) --> Nasal Cavity --> Inferior, Superior, & Middle Nasal Conchae --> Pharynx --> Larynx --> Trachea --> Primary Bronchi (Left & Right) --> Hilus --> Bronchioles --> Respiratory Bronchioles --> Alveolar Ducts --> Alveoli (the grape-like sacs) --> the the "spider web" of Pulmonary Capillaries.
What is A-a DO2?
Alveolar-arterial oxygen difference (A-a)DO2
Site of alveolar-capillary oxygen exchange?
Within the lungs.
Explain how changes in the alveolar structure cause a decrease in the blood oxygen levels in emphysema?
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.
What molecule is the source of oxygen?
oxygen is a molecule
Where do blood cells pick up oxygen?
In the lungs, in the alveolar capillaries
Where is oxygen transferred to?
Oxygen is transferred to hemoglobin at the alveolar/capillary function. This transfer occurs through diffusion.
How many protons are in an oxygen molecule?
There are 8 protons in an oxygen atom. There are two oxygen atoms in an oxygen molecule. Therefore, there are 16 protons in an oxygen molecule
How do you describe carbon dioxide gas?
In CO2 molecule, one molecule of carbon is bonded to two oxygen by two double bonds,which is as follows O=C=O
Would breathing pure oxygen cause a large increase in oxygen transport by the blood in a person with a low alveolar oxygen?
We know that our blood has a pigment called Haemoglobin,which gives characteristic red colour to blood.A haemoglobin molecule carries a maximum of 4 oxygen molecules,and is called 100% saturated when it does so.So,breathing pure oxygen doesn't increase the transport of oxygen.
Is an oxygen molecule an organic molecule?
No, it's not organic (an organic molecule has to contain carbon.)
Why does oxygen diffusion from the alveolus to the alveolar capillary occur?
Diffusion (of anything) occurs because of a concentration gradient meaning there is more oxygen in one place than another. Alveolus when you inhale will have a higher concentration of oxygen that that of the alveolar capillary resulting in a concentration gradient, this causing diffusion to occur until equilibrium is met. This means more oxygen in alveolus so oxygen travels into the alveolar capillary until a balanced amount of oxygen is in both places, but then of course the oxygen is transported and you exhale and inhale so the process repeats.
