Elena-2011 [213]

c)distance between two of the numbered lines

Explanation:

On a meter stick, a centimeter is usually the distance between two of the numbered lines. A meter stick is a device for measuring the length of an object.

A hundred centimeters makes up a meter and this is the number of divisions on a meter stick.
Each distance between numbered vertical lines is a centimeter apart.
On a meter stick that is 1m long, there are 100cm.

The internal energy of 10 moles of helium (a monatomic gas) is 15 kJ. What is the rms speed of the molecules? (The molar mass of

Radda [10]

Answer:

$v_{rms}=866.32m/s$

Explanation:

Hello,

In this case, since the rms speed of the molecules is computed by:

$v_{rms}=\sqrt{\frac{3RT}{M} }$

Whereas the absolute temperature is computed from the internal energy (by using the Cp of helium (3.1156 J/g*K) as shown below:

$U=nCvT\\\\T=\frac{U}{nCv}=\frac{15kJ*\frac{1000J}{1kJ} }{10mol*\frac{4.00g}{1mol} *3.1156\frac{J}{g*K} } \\\\T=120.36K$

Thereby, the rms speed results:

$v_{rms}=\sqrt{\frac{3*8.314\frac{kg*m^2}{s^2*mol*K}*120.36K}{4.00\frac{g}{mol}*\frac{1kg}{1000} } } \\\\v_{rms}=866.32m/s$

Regards.

T OR F<br> a molecule contains 2 or more polar bonds, than the entire molecule is never nonpolar.

PolarNik [594]

False

Explanation:

A molecule containing two or more polar bonds in its entire structure is a polar molecule. What determines the polarity of bonds in molecules their net dipole moment.

In elements combination, the electronegativity difference between two atoms determines polarity.
In a bonded specie, polarity of a molecule is determined by the net dipole moment.
The net dipole moment depends on the geometry of the molecule.
If the geometry favors the formation of polar bonds, the molecule will be polar.
