<span>Electron cloud model was the great contribution of 20th centuary
</span><span>In the electron cloud model, the electron cloud is denser in some locations than in others the denser areas represent that the
</span><span>regions where the probability of finding an electron is high
</span>means there is more chance of finding or presence of an electron
so correct option is A

We need two pieces of information to calculate the reduction of the
vapor pressure of the solvent in a solution containing a nonvolatile
nonelectrolyte:
<span>
<span>The mole fraction of the
nonvolatile solute, Xsolute, in the solution.</span>
<span>The vapor pressure of the
pure solvent, Psolv.</span>
</span>
Psoln = Psolvent (1- Xsolute)
Xsolute = (100g /342.3 g/ mol) / ( 100g
/342.3 g/ mol) + (250 g/ 18 g/ mol)
X solute = 0.0206
P soln = (23.8 mmHg) (1- 0.0206)
Psoln = 23.31 mmg Hg

Atmospheric pressure increases as altitude increases therefore boiling time will need to be extended
Answer:
All strong acids have a higher value of and the equilibrium for the reaction with water lies far to the right.
Explanation:
All strong acids dissociate completely in the solution. Higher the value of dissociation constant of the acid, higher will be the dissociation of the acid.
The reaction of the acid with water will be favored in the forward direction for acids having higher dissociation constant value ().
The dissociation of a strong acid say HA in water is shown below
Higher the value of , more will be the dissociation of the acid in water. The reaction will move far to the right side.
