Answer:
When the pressure increases to 90.0 atm , the volume of the sample is 0.01467L
Explanation:
To answer the question, we note that
P₁ = 1.00 atm
V₁ = 1.32 L
P₂ = 90 atm.
According to Boyle's law, at constant temperature, the volume of gas is inversely proportional to its pressure
That is P₁V₁ = P₂V₂
Solving the above equation for V₂ we have
that is V₂ =
=
or 0.01467L
Answer and Explanation:
The resonance contributor in cyclopentadienone (as shown in the attachment below) results into the compound having a positive charge on the carbonyl group, C=O which accounts for a highly reactive anti-aromatic 4π system. And this illustrates the reason for its instability.
Answer:
The solution has a higher osmotic pressure and higher boiling point than LiCl solution.
Explanation:
As concentrations of two aqueous solutions are same therefore we can write:
,
and
where ,
and
are lowering of vapor pressure, elevation in boiling point and osmotic pressure of solution respectively.
is van't hoff factor.
= total number of ions generated from dissolution of one molecule of a substance (for strong electrolyte).
Here both and LiCl are strong electrolytes.
So, and
Hence, lowering of vapor pressure, elevation in boiling point and osmotic pressure will be higher for solution.
Therefore the solution has a higher osmotic pressure and higher boiling point than LiCl solution.
I don't know how 5°C cooled to 85°C but the answer would be 12.878L
