A volume of nitrogen gas has a density of 1.301.30 kg/m3 and a pressure of 1.151.15 atm. Find the temperature of the gas and the

Alexus [3.1K]

Answer :

The temperature of the gas is, 301.7 K

The root mean square speed is, $5.18\times 10^{2}m/s$

Explanation :

To calculate the volume of argon gas we are using ideal gas equation:

$PV=nRT\\\\PV=\frac{w}{M}RT\\\\P=\frac{w}{V}\times \frac{RT}{M}\\\\P=\frac{\rho RT}{M}$

where,

P = pressure of nitrogen gas = 1.15 atm

V = volume of nitrogen gas

T = temperature of nitrogen gas

R = gas constant = 0.0821 L.atm/mole.K

w = mass of nitrogen gas

M = molar mass of nitrogen gas = 28 g/mole

$\rho$ = density of nitrogen gas = $1.30kg/m^3=1.30g/L$

Now put all the given values in the ideal gas equation, we get:

$1.15atm=\frac{(1.30g/L)\times (0.0821L.atm/mole.K)\times T}{28g/mol}$

$T=301.7K$

Therefore, the temperature of the gas is, 301.7 K

Now we have to determine the root mean square speed of the molecule.

The formula used for root mean square speed is:

$\nu_{rms}=\sqrt{\frac{3kN_AT}{M}}$

where,

$\nu_{rms}$ = root mean square speed

k = Boltzmann’s constant = $1.38\times 10^{-23}J/K$

T = temperature = 301.7 K

M = atomic mass of nitrogen gas = 0.028 kg/mole

$N_A$ = Avogadro’s number = $6.02\times 10^{23}mol^{-1}$

Now put all the given values in the above root mean square speed formula, we get:

$\nu_{rms}=\sqrt{\frac{3\times (1.38\times 10^{-23}J/K)\times (6.02\times 10^{23}mol^{-1})\times (301.7K)}{0.028kg/mol}}$

$\nu_{rms}=5.18\times 10^{2}m/s$

The root mean square speed is, $5.18\times 10^{2}m/s$

Help!!!!!!<br> I'm using plato

Masja [62]

Answer:

Freezing

Melting

Condensation

Evaporation

Sublimation

Deposition

Explanation:

From the diagram,

(1) Liquid⇒Solid (Freezing)

Freezing: This is the process by through which a substance change from liquid to solid.

(2) Solid⇒Liquid (Melting)

Melting: This is a process through which a substance change from solid to liquid

(3) Liquid⇒gas (Evaporation)

Evaporation: This is a process through which a substance change from liquid to gas.

(4) gas⇒Liquid (Condensation)

Condensation: This is a process through which a substance change from gas to liquid

(5) Solid⇒gas (Sublimation)

Sublimation: this is a process through which a subtance change from solid to gas

(6) gas⇒solid (Deposition)

Deposition: This is a process through which gas transform into solid.

A hydrogen atom is removed from the first carbon atom of a butane molecule and is replaced by a hydroxyl group. draw the new mol

Leno4ka [110]

The new molecule that is formed is an alcohol and is known as butanol. It has a chemical formula CH3CH2CH2CH2OH or C4H9<span>OH</span>. A molecule that has a hydroxyl functional group is an alcohol. It has isomers namely tert-butanol, 2-butanol and isobutanol.

Which molecule could have an expanded octet? hno2 h2co3 h3po4?

schepotkina [342]

The molecule that can have an expanded octet is H3PO4.
An expanded octet refers to a situation in which a compound has more than the required number of valence electrons in its outermost shell. The required number of valence electron is 8 but a compound with an expanded octet can have up to 35 electrons in its outermost shell. An example of such a compound is H3PO4, which has 32 valence electrons in its outermost shell.
