Answer:
Explanation:
Elevation in boiling point is given by:
= Elevation in boiling point
i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)
= freezing point constant =
m= molality
Weight of solvent (water)= 1.000 kg
Molar mass of solute = 142 g/mol
Mass of solute = 175.0 g
Thus the boiling point of water when 175.0 g of , a strong electrolyte is dissolved in 1.000 Kg of water is
Answer:
Option C.
Explanation:
The arrangement of electrons in their orbital follows certain rules.
The Hund's rule practically explained how electrons are distributed in their orbitals.
The Hund's rule states that electrons distributed among the orbitals of the same shell singly (without partner) before pairing occurs.
In the filling of these electrons in their orbitals, we fill in the electron without pairing first because electrons tends to repel each other before filling with the opposite spin as shown in the attached photo.
