Answer:
0.43 atm
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 0.95 atm
Initial volume (V₁) = 0.55 L
Final volume (V₂) = 1.22 L
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as follow:
P₁V₁ = P₂V₂
0.95 × 0.55 = P₂ × 1.22
0.5225 = P₂ × 1.22
Divide both side by 1.22
P₂ = 0.5225 / 1.22
P₂ = 0.43 atm
Therefore, the final pressure of the gas is 0.43 atm
Answer:
(c) an aqueous solution of CO2 exhibits dipole-dipole forces between solute and solvent
Explanation:
Co2 is a non-polar molecule.
It is actually shown to be O=C=O.
When dissolved in water to get aqueous solution.
Dipole on water molecule can induce dipole on CO2.
This entails that we should have dipole-induced dipole forces when we have a mixture or solvent and solute.
But the given statement states dipole dipole forces between solute and solvent.
Hence the statement is false.
