calculate the translational partition function of xenon and helium at the them temperature and volume

Chemistry
1 answer:
son4ous [18]3 years ago
4 0

Explanation:

a) The ratio of the translational partition of D2 and H2 is 2.82

b) The ratio of the translational partition of xenon and helium is 187.56

Explanation:

a) The translational partition for D₂ is equal to:

Where

m = mass of molecule

k = Boltzmann constant

T = absolute temperature

V = volume of container

h = Planck constant

If rewrite the equation:

The same for the H₂ molecule:

Taking the ratio D₂ and H₂:

Where

mH₂ = 2.015894 amu

mD₂ = 4.028204 amu

b) The same way to part a)

Which element would be expected to have similar physical and chemical properties as oxygen, and why? nitrogen, because it's in t
mamaluj [8]
<span>sulfur, because it's in the same group

Groups are columns of a periodic table. Both oxygen and sulfur are in the same group, and groups, such as halogens and noble gases, generally display similar properties. Periods are ordered by ascending atomic number, and don't typically display the same level of similarity. </span>

what is the temperature in Kelvin of 5.00 moles of nitrogen gas in a 30 L container with a pressure of 4.00 atm
Marianna [84]

The temperature of the nitrogen gas is 292.5 K.

<u>Explanation:</u>

Given that

Moles of Nitrogen, n = 5 mol

Volume, V = 30 L

Pressure, P = 4 atm

Gas Constant, R = 0.08205 L atm mol⁻¹ K⁻¹

Temperature = ? K

We have to use the ideal gas equation,

PV = nRT

by rearranging the equation, so that the equation becomes,

T = $\frac{PV}{nR}\\

Plugin the above values, we will get,

T = $\frac{4 \times 30}{5 \times 0.08205}

  = 292.5 K

So the temperature of the nitrogen gas is 292.5 K.

How many grams of KBr is required to prepare 100 mL of<br> 2.0 M KBr solution?
sesenic [268]

Answer:

23.8g

Explanation :

Convert 2.0M into mol using mol= concentration x volume

2.0M x 0.1L (convert 100mL to L since the units for M is mol/L)

= 0.2 mol

We can now find grams by using the molar mass of KBr

=119.023 g/mol (Found online) webqc.org

but can be be calculated by using the molecular weight of K and Br found on the periodic table

We can now calculate the grams by using grams=mol x molar mass

119.023g/mol x 0.2mol

= 23.8046 g

=23.8g (rounded to 1decimal place)
