Answer:
SO3 is a nonpolar molecule and SO2 is a polar molecule.
Explanation:
As can be seen in the attached, the SO3 molecule has a trigonal planar geometry. Each individual double bond of S=O is polar but the molecule has symmetrical geometry so the dipole momentums are canceled.
On the other hand, the SO2 molecule has a trigonal planar electron geometry but an angular molecular geometry due to the unbound electron pair. This unbound electron pair creates a total dipole momentum with negative density over the electron pair.
Answer:
5 moles of Argon is present in the mixture.
Explanation:
Total pressure of the gaseous mixture = 4 atm
Total number of moles = 16
Partial pressure of Ne = 2.75 atm
By Dalton's law of partial pressure, the total pressure of gaseous mixture is the sum of partial pressures of individual gases which are non-reactive.
Hence:
Also :
Partial pressure = mole fraction*total pressure
∴Number of moles of Argon = 5
