Answer:

Ka= 2.3 x 10^-11

Explanation:

so Ka x Kb = Kw where Kw=10^-14 at 25 degrees Celsius

plugging in Kb and Kw, we have

Ka x 4.4 x 10^-4 = 10^-14

solving for Ka,

Ka= (10^-14)/(4.4 x 10^-4)

Ka= 2.3 x 10^-11

create visual representations that show the interactions between the particles in both samples during vaporization
ivolga24 [154]

Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.

<h3>What is vaporization?</h3>
  • Vaporization is the changing of a liquid into a gas.
  • This is known as a phase change.
  • This happens when the atoms receive enough heat energy.
  • The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
  • When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.

Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.
