What type of forces mustiness(prenominal) 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 bondingWhat type of forces represent between I2 and CH3OH molecules in solution?Dipole-Induced Dipole4) What type of intermolecular forces must be overcome in converting each of the following from a liquid to a bollocks?a) CO2 capital of the United Kingdom forces, dipole-dipoleb) NH3 London forces, dipole-dipole, hydrogenc) CHCl3 London forces, dipole-dipoled) CCl4 London forces6) Rank the following in order of increasing personnel of intermolecular forces in the pure inwardnesss. Which mettle exists as a gas at 25 C and 1 atm?He CH3OH CH3CH2CH2CH3He (helium) and CH3CH2CH2CH3 (butane) exist as a gas at 25 C and 1 atm12) The enthalpy of vaporization of liquid hectogram is 59.11kJ/mol. What cadence of energy as heat is required to vaporize 0.500 mL of mercury at 357C, its nor mal boiling point? The density of mercury is 13.6 g/mL.2.0 kJ16) Figure 12.17a) 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 andvapor remain constant.b) assuming that the temperature your heap is below 34.6 degrees Celsius, liquid diethyl ether should remain a liquid if dropped on your hand.22) Vapor pressure data for octane C8H1838.6 kJ/mol, normal boiling point 128 C26) What factors affect the viscosity of a substance?Temperature, size of the molecule, polarity, and the amount of substance present affect viscosity. Which of the following substances is expected to have the highest viscosity? glycerine has the highest viscosity because it has the greatest amount of intermolecular forces.Should viscosity of a substance be affected by temperature? Explain. As the temperature of a liquid increases the energizing e nergy required to separate the intermolecular forces also increases. The amount of insularism that occurs is a measure of the viscosity, the opposite effect occurs when a liquid is cooled as the energy level is minimal.
