Liquid A is known to have a higher vapor pressure and higher surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 25.0 mL of Liquid A are poured into a beaker. 25.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and VB of liquid in A each beaker are measured. 25.0 mL of Liquid A are put in one sealed 5 L flask, and 25.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. A A predicted outcome will be greater than VB will be less than VB will be equal to B It's impossible to predict whether VA or V will be greater without more information. O Eventually both liquids boil, A first and then B. O Eventually both liquids boil, B first and then A. O Neither liquid will boil It's impossible to predict whether eitherliquid boils without more information.

11.Why do water molecules tend to stick to each other to form a liquid?     A.Because of their bent shape, the oxygen nucleus of one molecule is unshielded and can attract the hydrogen nucleus of another.   B.The exposed charge on hydrogen's protons are attracted to unshared electron pairs on oxygen atoms.    C.The hydrogen atoms form negative ions that can make ionic bonds with oxygen.   D.Water molecules can share electrons with neighboring molecules forming strong covalent bonds.

= STATES OF MATTER Understanding consequences of important physical properties ... Liquid A is known to have a higher vapor pressure and higher surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 35.0 mL of Liquid A are put in one sealed 5 L flask, and 35.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. 35.0 mL of Liquid A are put in one sealed 5 L flask, and 35.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is slowly increased by pumping in argon gas. O predicted outcome Eventually both liquids boil, A first and then B. Eventually both liquids boil, B first and then A.

The pressure above a pure sample of solid Substance X at -186. °C is lowered. At what pressure will the sample sublime? Use the phase diagram of X below to find your answer. pressure (atm) 0 atm بات solid 100 liquid 200 x gas temperature (K) Note: your answer must be within 2 atm of the exact answer to be graded correct. 300
