A solution is made by mixing 33.0 ml of ethanol, C2H6O and 67.0 ml of water. Assuming ideal behavior, what is the vapor pressure
ivann1987 [24]
Grams ethanol = 33 ml times .789 gms/ml = 26.037 gms 

<span>Moles ethanol = 26.037 gms / 46 gms/mole = .57 moles </span>

<span>Moles water = 67 ml or 67 grams/18 gms/mole = 3.22 moles </span>

<span>total moles = .57 + 3.72 = 4.29 moles </span>

<span>Mole fraction ethanol = .57 moles ethanol / 4.29 moles total = 0.13</span>

<span>Moles fraction water = 3.72 moles water / 4.29 moles total = 0.87</span>

<span>Partial pressure of ethanol = mole fraction ethanol (.13) _ times VP ethanol 43.9 torr) = 5.707 torr </span>

<span>partial pressure water = mole fraction water .87) times VP water (l7.5 torr) = 15.23 torr </span>

<span>Total vapor pressure over solution = 5.71 torr + 15.23 torr = 20.94 torr</span>

Examine the incomplete statement.
hjlf

Answer: Option (c) is the correct answer.

Explanation:

In liquids, molecules are held by slightly less strong intermolecular forces of attraction as compared to solids.

Hence, molecules of a liquid are able to slide past each other as they have more kinetic energy than the molecules of a solid.

As a result, liquids are able to occupy the shape of container in which they are placed. Also, liquids have fixed volume but no fixed shape.

Thus, we can conclude that liquids have a variable shape and a fixed volume.

Slav-nsk [51]

Answer: Please see explanation for answer

Explanation:Matching the  descriptions to the correct element listed gives

Element Group Name Group No Metal/ Nonmetal/ Metalloid Description

Neon    Noble gases       18           Non metal Colorless, tasteless, and        odorless gas, unreactive, nonconductive.

Bromine      Halogens   17          Non metal Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor.

Beryllium       Alklaline earth metal  2    Metal  Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element

Platinum     Platimum group metals  10   Metal      Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel

Potassium   Alkali Metals   1   Metal  Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature

Silicon    Carbon family     1`4  Metalloid   Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor

Sulfur   Calcogens      16  Non metal  Pale yellow, odorless, brittle solid at room temperature, nonconductor
