H2 does not have a coefficient.
When writing chemical equations, coefficient refers to the numerical values written at the back of each compound, which show the number of molecule of each substance that is involved in the reaction. For instance, in 2H20, 2 is the cofficient, which tell us that two molecules of water is involved.
In the question given, the figure 2 attached to the symbol H is a subscript, which shows the number of atoms in the hydrogen molecule.

What is the charecteristics of an alveolus

Alla [95]

Each alveolus is cup-shaped with very thin walls.
It’s surrounded by networks of blood vessels called capillaries that also have thin walls.
The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
The carbon dioxide you breathe out is diffused from the capillaries to the alveoli, up the bronchial tree and out your mouth.
The alveoli are just one cell in thickness, which allows the gas exchange of respiration to take place rapidly.
