Which molecule has a lewis structure that does not obey the octet rule?

Chemistry
1 answer:
Zepler [3.9K]3 years ago
5 0
I believe a possible Lewis dot structure that does not obey the octet rule, where all elements are required to have 8 electrons in their outermost shell, would be the SF4 molecule.

Sulfur can contain an more than 8 electrons, in this molecule and thus has an expanded octet.

DerKrebs [107]

#AB

Electronegativity difference=3.3-2.9=0.4.

  • It's a covalent bond.
  • Gaseous or solid substance.

#AC

Electronegativity difference=3.3-0.7=2.6

  • Its an ionic bond.
  • Solid substance.

#BC

Electronegativity difference=2.9-0.7=2.3

  • It's an ionic bond
  • Solid substance

A 8.96-L sample of gas has a pressure of 1.86 atm and a temperature of 94 °C. The sample is allowed to expand to a volume of 11.
Varvara68 [4.7K]

Answer:

Explanation:

Explanation:

All you have to do here is use the ideal gas law equation, which looks like this

P

V

=

n

R

T

−−−−−−−−−−

Here

P

is the pressure of the gas

V

is the volume it occupies

n

is the number of moles of gas present in the sample

R

is the universal gas constant, equal to

0.0821

atm L

mol K

T

is the absolute temperature of the gas

Rearrange the equation to solve for

T

P

V

=

n

R

T

⇒

T

=

P

V

n

R

Before plugging in your values, make sure that the units given to you match those used in the expression of the universal gas constant.

In this case, the volume is given in liters and the pressure in atmospheres, so you're good to go.

Plug in your values to find

T

=

3.10
