Electrons are shared between two ions in covalent bonds. Hydrogen bonding isn't a 'true' bond, as electrons aren't shared or exchanged. Instead, the hydrogen on one atom is strongly attracted to a highly electronegative atom (like F, O, N) on an adjacent molecule.  The result is a strong attractive force between the adjacent atoms.

FYI - this explains why a low molecular weight polar substance like water (H2O) has a significantly higher boiling point than other nonpolar molecules of similar molecular weight. More energy has to be added to the system to overcome the attractive forces between the molecules of water.

Calculate the partial pressure of the CO2 in the expired air at its peak, assuming 1 atm pressure and a body temperature of 37∘C
kvasek [131]

Answer:

P2= 45.50 atm

Explanation:

If the amount of gas in the tanks remains same we use the equation P1T1=P2T2

40 x 281.15 = P2 x 247.15

P2= 45.50 atm

for the given reaction, what volume of o2 would be required to react with 4.8 l of co , measured at the same temperature and pre
SVEN [57.7K]

We can see that 2 moles of The no react with 1 mole of O2 using this equation. 4.8 L NO x 1 L O2 / 2 L NO = 2.4 L of O2 are needed at constant pressure and temperature.

What is an example of pressure?

One can see a simple illustration of pressure by using a knife against a few fruit. If you press the flat side of the knife against the fruit, the top won't be cut. The force is spread more than a wide area (low pressure).

What are different types of pressure?

The physical pressure exerted to an object is referred to as pressure. Per unit area, a parallel force is applied to the surface of the objects. F/A (Force per Area) is the basic formula for pressure.
