Abond that is not symmetrical along the axis between two atomic nuclei is a(n)
a. alpha bond
c. pi bond
b. sigma bond
d. beta bond

c. pi bond

Explanation:

Pi bonds are formed by the sideway overlap of two s-s atomic orbital or s-p atomic orbital. Pi bonds are covalent bonds which involves the mutual sharing of electrons between two non-metals. Pi bond is unsymmetrical along the axis between two atomic nuclei.

Sigma bond on the other hand involves a head on overlap of two s-s atomic orbital or s-p atomic orbital. Sigma bond is symmetrical along the axis between two atomic nuclei.

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
