Explanation:

<h3>Atomic Number and Mass</h3>

Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.

Option A.

Explanation:

For part A

The applicable equation is the Clausius-Clapeyron equation. The equation relates the vapor pressure and temperature like this:

$ln(\frac{P_{2} }{P_{1} } = \frac{\deltaH_{vap} }{R} * (\frac{1}{T_{2} } - \frac{1}{T_{1}) }$

We know that P₁ = 6.63 torr

R = 8.314 kj/mol

T₁ = 106.5⁰ = 379.65 K

T₂ = 38⁰ = 311.15 K

ΔH = 43 300J/mol

using the equation to solve for P₂, we get 67.8 torr

For part B

Water is a polar molecule. The bonds in the water are hydrogen bonds; water forms strong hydrogen bonds between the molecules. However, the gases in the air are non polar. Nitrogen and argon are inert gases - nonreactive. Nitrogen has a triple bond N≡N and argon is inert. Oxygen is a bi-atomic gas, O₂.

Hence the only forces in the water with the gases are dipole-induced dipole forces.

I think it’s an ionic compound? An example is salt because water breaks it up due to the polar bonds.
NaCl = [Na+] + [Cl-]
Those conduct electricity.
