Explanation:
From the scattering experiments, Rutherford concluded that the positive charge was concentrated in the nucleus of the atom.
This contradicted the plum pudding model, which assumed that the positive charge was uniformly distributed throughout the atom.
Answer: 26.8 kJ of energy is needed to vaporize 75.0 g of diethyl ether
Explanation:
First we have to calculate the moles of diethyl ether
As, 1 mole of diethyl ether require heat = 26.5 kJ
So, 1.01 moles of diethyl ether require heat =
Thus 26.8 kJ of energy is needed to vaporize 75.0 g of diethyl ether
