2) What type of forces must be overcome when solid I2 dissolves in methanol, CH3OH? Induced dipole What type of forces must be disrupted between CH3OH molecules when I2 dissolves? Hydrogen bonding What type of forces exist between I2 and CH3OH molecules in solution? Dipole-Induced Dipole
4) What type of intermolecular forces must be overcome in converting each of the following from a liquid to a gas? a) CO2 London forces, dipole-dipole b) NH3 London forces, dipole-dipole, hydrogen c) CHCl3 London forces, dipole-dipole d) CCl4 London forces
6) Rank the following in order of increasing strength of intermolecular forces in the pure substances. Which substance exists as a gas at 25 ®C and 1 atm? …show more content…
What quantity of energy as heat is required to vaporize 0.500 mL of mercury at 357®C, its normal boiling point? The density of mercury is 13.6 g/mL. 2.0 kJ 16) Figure 12.17 a) if water is placed in a sealed milk carton at 60 degrees Celsius and sealed tightly and allowed to cool, eventually there will be an equilibrium of liquid and vapor. Gas is not able to escape and masses of the liquid and vapor remain constant.
b) assuming that the temperature your hand is below 34.6 degrees Celsius, liquid diethyl ether should remain a liquid if dropped on your hand.
22) Vapor pressure data for octane C8H18 38.6 kJ/mol, normal boiling point 128® C
26) What factors affect the viscosity of a substance? Temperature, size of the molecule, polarity, and the amount of substance present affect
