How does atom electronegativity affect bond character and molecular polarity?

Explanation:

Electronegativity is defined as the ability of an atom to attract electrons towards itself.

When atoms of a compound or molecule attain partial charges due to the difference in their electronegativity then it is known as molecular polarity.

More is the electronegativity of the combining atoms more ionic bond character the compound will have.

For example, HCl is an ionic compound.

Whereas less is the difference between electronegativity of combining atoms more covalent character the compound will have.

For example, is a covalent compound.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
