(a)
Interpretation:
The structures of the four given molecules must be drawn indicating whether those are polar or non polar.
Concept Introduction:
Lewis structure is the representation of molecules showing the electron dots present in each atom.
A polar molecule has non zero bond moments whereas a non polar molecule has zero bond moments.
(b)
Interpretation:
Which two molecules are liquid and which two are gases as room temperature must be predicted along with proper explanation.
Concept Introduction:
For liquids intermolecular forces are stronger as compared to gases.
(c)
Interpretation:
The given compounds must be ranked from lowest to highest boiling point with proper justification.
Concept Introduction:
Molecules having stronger intermolecular forces show higher boiling points.

- Calculate the partial pressure of the H2 gas collected (atm). Remember to correct for the water vapor (Table 1).arrow_forwardLiquified petroleum gas (LPG) is propane stored under sufficient pressure to liquify it. When a tank of LPG is opened the propane vaporizes and is released as gas-phase propane. a) If a 50.0 g sample of LPG is released into an otherwise empty cylinder with a piston, what volume of gas is produced at 1.00 atm and 25.0 oC? b) If the resulting gas (assume ideal behavior) sample is heated to 50 oC while simultaneously doubling the pressure, what is the volume that the gas occupies? c) Briefly explain what effect this i) heating, and ii) pressurizing, of the gas will do to the average kinetic energy of the propane.arrow_forwardWhich of the following would be expected to have the lowest vapor pressure at room temperature? ethanol, bp = 78°C methanol, bp = 65°C water, bp = 100°C acetone, bp = 56°Carrow_forward

H₂CO₃(aq) → H₂O(l) + CO₂(g)arrow_forwardArrange the following substances in order of increasing total intermolecular forces between their molecules. ○ | < 1 < ||| OI< | < | ○ | < | < 1 O # < 1< || O | < | < 1 Ol< | < | I OH 11 111 OHarrow_forward
- Which statement best describes the structure of water and its nature as a solvent? O The water molecule is polar and will dissolve polar molecules, such as sugar. O The water molecule is polar and will not dissolve ionic compounds, such as salt. The water molecule is nonpolar and will dissolve polar molecules, such as vinegar. O The water molecule is nonpolar and will dissolve nonpolar molecules, such as oil.arrow_forwardUse vapor pressure. A student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.76 m × 4.17 m × 3.31 m and the student places a pan containing 1.62 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains a constant 25 °C. The vapor pressure of water at 25 °C is 23.8 mm Hg. (a) Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. mm Hg (b) Will all of the water in the pan evaporate?arrow_forwardExplain each of these properties of water, and describe how each is conferred by the dipolar nature of a water molecule: high specific heat capacity; high heat of vaporization; unique density behavior; high surface tension; capacity to be a good solvent for ions of salts.arrow_forward
- Write the Lewis structure(s), predict the molecular/ion shape (eg. linear) , and the types of intermolecular forces present (Choose from London dispersion forces, Dipole-dipole, Hydrogen bonding) of the following molecules and ions to complete the table below.

The only intermolecular force of attraction that exists between diatomic oxygen molecules (O2) is London dispersion forces.arrow_forwardUse vapor pressure. A student leaving campus for spring break wants to make sure the air in his dorm room has a high water vapor pressure so that his plants are comfortable. The dorm room measures 3.41 mx 4.41 m x 3.90 m and the student places a pan containing 0.874 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when he closes the door, and that the temperature remains a constant 22 °C. The vapor pressure of water at 22 °C is 19.8 mm Hg.
