After hydrogen bonding the strongest intermolecular force would be ___

1 answer:

The answer is van der Waal force, or to be precise, London dispersion forces.

This type of force is present between all molecules and they are caused by electrons that are orbiting the atom cores. The moving of the electrons can result in making the atom temporary dipole due to the asymmetry of electron distribution around the core. This temporary dipole now can interact with other atoms leading to an electrostatic interaction. The more electrons an atom has, the stronger are these intermolecular forces.

What volume change occurs to a 400.0 mL gas sample as the temperature increases from 22.0 °C to 30.0°C?

nasty-shy [4]

V₁ = 400.0 mL

T₁ = 22.0ºC + 273 = 295 K

V₂ = ?

T₂ = 30.0ºC + 273 = 303 K

V₁ / T₁ = V₂ / T₂

400.0 / 295 = V₂ / 303

295 x V₂ = 400.0 x 303

295 V₂ = 121200

V₂ = 121200 / 295

V₂ = 410.84 mL

hope this helps!

A gaseous mixture at 265K and 1.0 atm contains 25 O2 60 N2 and 15 CO2 mole basis The velocities of the components are 0.084 cm s

Free_Kalibri [48]

Answer:

The molar average velocity is 0.0588 cm/s

The N₂ diffusion velocity relative to the mole average velocity is -0.1428 cm/s

The molar diffusional flux of N₂ is -3.9x10⁻³

Explanation:

Given data:

T = temperature = 265 K

O₂ = 25%

N₂ = 60%

CO₂ = 15%

vO₂ = -0.084 cm/s

vN₂ = 0.12 cm/s

vCO₂ = 0.052 cm/s

The molar average velocity is equal:

$v_{av} =(0.25*(-0.084))+(0.6*0.12)+(0.15*0.052)=0.0588cm/s$

The N₂ diffusion velocity relative to the molar average velocity is:

$v_{i} -v_{av} =-0.084-0.0588=-0.1428cm/s$

The molar diffusional flux of N₂ is:

$N_{N_{2} } =\frac{P}{RT} y_{A} (v_{i} -v_{av} )=-3.9x10^{-3}$
