What is the vapor pressure (in kPa) of ethanol, CH3CH2OH, over a solution which is composed of 18.00 mL of ethanol and 12.55 g o
ladessa [460]

Answer:

The vapor pressure of ethanol in the solution is 10,27 kPa

Explanation:

To obtain the vapor pressure of a solution it is necessary to use Raoult's law:

P_{solution} = X{solvent}P_{0solvent} <em>(1)</em>

The moles of ethanol are:

18,00mL×\frac{0,789g}{1mL}×\frac{1 mol}{46,07g} = 0,3083 mol Ethanol.

Moles of benzoic acid:

12,55 g×\frac{1mol}{122,12g} = 0,1028 mol benzoic acid.

Thus, mole fraction of solvent, X, is:

\frac{0,3083 mol}{0,3083mol+0,1028mol} =<em> 0,7499</em>

Replacing this value in (1):

P_{solution} = 0,7499*13,693kPa = <em>10,27 kPa</em>

<em></em>

I hope it helps!

Why might a metallic compound be mistaken for an ionic compound, based on its physical properties?
devlian [24]

Answer:

(D). Both metallic and ionic compounds can conduct electricity when molten. However, only metallic compounds can conduct electricity in a solid state.

Explanation:

Metallic compound have the ability to conduct electricity. Since they are Metals they have loosely held electrons which can contribute to electricity conduction.

Ionic compound are brittle physically, ionic compound cannot conduct electricity while being in solid state as the ions are held strongly by electrostatic force of attraction, they can only conduct electricity while they are in molten or aqueous state. In molten state they are forming ions, and ions are free to move within the solution and therefore contribute to electricity conduction.
