Answer: No, the noble gases are

Explanation:

Annette [7]3 years ago
3 0

Answer:

The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.

Polar or Nonglar? SO_3 SO_2
Evgesh-ka [11]

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.

A gas mixture of Ne and Ar has a total pressure of 4.00 atm and contains 16.0 mol of gas. If the partial pressure of Ne is 2.75
Stolb23 [73]

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:

P_{total}=P_{Ar}+P_{Ne}\\4=P_{Ar}+2.75\\P_{Ar}=1.25\ atm

Also :

Partial pressure = mole fraction*total pressure

P_{Ar}=X_{Ar}P_{total}

X_{Ar}=\frac{1.25}{4}=0.3125

\frac{n_{Ar}}{n_{total}}=0.3125\\n_{Ar}=5

∴Number of moles of Argon = 5
