Answer:
energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.

Answer:
b. ICl experiences dipole-dipole interactions
Explanation:
The molecule with the <em>stronger intermolecular forces</em> will have the higher boiling point.
In Br₂, the Br-Br bond has a <em>dipole moment of zero</em>, because the two atoms are identical.
In ICl, the I-Cl bond, has two different atoms. One must be more electronegative than the other, so there will be a <em>non-zero bond dipole</em>.
ICl will have the higher boiling point.
a is <em>wrong</em>. Br₂ is nonpolar, so it has no dipole-dipole interactions.
c is <em>wrong</em>. Br₂ cannot form hydrogen bonds, because there is no hydrogen.
d is <em>wrong</em>. ICl has dipole-dipole interactions.
<span>The molar volume of a gas at STP, in liters, is 22.4
you then multiply 22.4 by 2 to get the answer to the next question:
</span><span>
You can use the molar volume to convert 2 mol of any gas to 44.8 L
</span>
<span>You can also use the molar volume to convert 11.2 L of any gas to 0.500 mol.
</span>
Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g<span>) are the same </span><span>numbers of moles of gas.</span>
