Answer:

V = 18.8 L

Explanation:

This question is solved by using the ideal gas law :

PV = nRT ∴  V= nRT/P

where n= 0.788 mmol = 0.788 mol (1 mmol is a thousandths of a mol)

R = R constant for ideal gases =  0.08206 Latm/Kmol

T = 17.0 ºC =  (17.0 + 273) K = 290 K

and V = volume in liters our unknown

Plugging our values and solving for V,

V = 0.788 mol x 0.08206 Latm/Kmol x 290 K / 1atm = 18.8 L

Which element is classified as a noble gas?<br> O<br> N<br> Cl<br> Xe
ivann1987 [24]

<u>Answer:</u> The correct answer is Xenon (Xe).

<u>Explanation:</u>

Noble gases are defined as the gases which have fully filled electronic configuration or stable electronic configuration.

From the given options:

<u>Option 1:</u> Oxygen (O)

The atomic number of this element is 8.

Electronic configuration of this element: 1s^22^22p^4

As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.

<u>Option 2:</u> Nitrogen (N)

The atomic number of this element is 7.

Electronic configuration of this element: 1s^22^22p^3

As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.

<u>Option 3:</u> Chlorine (Cl)

The atomic number of this element is 17.

Electronic configuration of this element: 1s^22^22p^63s^23p^5

As, this is not the stable electronic configuration. Thus, it is not considered as a noble gas.

<u>Option 4:</u> Xenon (Xe)

The atomic number of this element is 54.

Electronic configuration of this element: [Kr]5s^24d^{10}5p^6

As, this is a stable electronic configuration. Thus, it is considered as a noble gas.

Hence, the correct answer is Xenon (Xe).
