I have seen this question before and the correct answer would be B
Hope this helped!!
Answer is: <span>when the solute is molecular, not ionic.
When the solute is ionic, formula contains t</span><span>he </span>van 't Hoff factor: ΔTf = Kf · m · i.
Van 't Hoff (i) is <span>the number of dissolved particles the solute produces and it is usually i = 2,3...
</span>For molecular compounds (most non-<span>electrolytes)</span> van't Hoff factor is equal one.

KE = 1687500 Joules or
KE = 1.6875 Megajoules :)
Answer:the drift velocity is directly proportional to current. The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. In general, an electron will propagate randomly in a conductor at the Fermi velocity.Mar 11, 2017
