The “fatal flaw” in Rutherford’s model of the atom was the idea that if the electrons were ________.
Wittaler [7]
The correct option is A. Rutherford model of the atom consider an atom to be made up of a central nucleus with electrons orbiting around it. The nucleus is considered to be tiny, heavy and its positively charged while the electrons are negatively charged. The shortcoming of this model is that it was not able to explain how the positive nucleus was not able to attract the negative electrons and pull them inside the nucleus.

Determine the freezing point of a 0.51 molal
Elan Coil [88]

Answer:

-65.897°C.

Explanation:

  • Adding solute to water causes depression of the boiling point.
  • The depression in freezing point (ΔTf) can be calculated using the relation: <em>ΔTf = Kf.m,</em>

where, ΔTf is the depression in freezing point of chloroform solution.

Kf is the molal depression constant of chloroform (Kf = 4.70°C.kg/mol).

m is the molality of the solution (m = 0.51 m).

∴ ΔTf = Kf.m = (4.70°C.kg/mol)(0.51 m) = 2.397°C.

∴ The freezing point of the solution = (freezing point of chloroform) - ΔTf = (-63.5°C) - (2.397°C) = -65.897°C.
