Chem 210 Final: Mastering Chem 2023 With C omplete Updated Solution Highest: Nh3 SbH3 AsH3 PH3 - answerThe hydrides of group 5A are NH3, PH3, AsH3, and SbH3. Arrange them from highest to lowest boiling point. Dispersion - answerWhat is the strongest type of intermolecular force present in H2? Co2 - answerIdentify the compound that does not have dipole -dipole forces as its strongest force. 1 and 2 - answerWhich of the following must be overcome during the boiling of acetonitrile, CH3CN? 1. dispersion forces 2. dipole -dipole forces 3. hydrogen b onds I>III>II - answerPlace the following compounds in order of decreasing strength of intermolecular forces. I. CH3CH2CH2CH2CH2CH3 II. (CH3)3CCH3 III. (CH3)3CCH2CH3 Ion-dipole force - answerWhat type of intermolecular force causes the dissolution of KF in water? dispersion forces and dipole -dipole forces - answerWhat Inter molecular forces are present in: HBr dispersion forces, dipole -dipole forces and hydrogen bonding - answerWhat Inter molecular forces are present in: CH3COOH only dispersion forces - answerWhat Inter molecular forces are present in: Br2 only dispersion forces - answerWhat Inter molecular forces are present in: He Xe - answerBased on the expected intermolecular forces, which noble gas has the highest boiling point? Ar Ne Chem 210 Final: Mastering Chem 2023 With C omplete Updated Solution Xe Kr CH3CH2CH2CH3 - answerChoose the substance with the lowest surface tension. C6H6 CH3CH2CH2CH3 CH3OH H2O (CH3)2CO CF4 > PF5 > BrF3 - answerPlace the following substances in order of decreasing vapor pressure at a given temperature. PF5 BrF3 CF4 Cal2 - answerChoose the substance with the lowest vapor pressure at a given temperature. Ar CO2 CaI2 BF3 PF5 44.4 kj/mol - answerPropanol has a normal boiling point of 97.8°C. At 400 torr, it has a boiling point of 82.0°C. What is the heat of vaporization? 24.9 k J/mol 38.7 kJ/mol 12.3 kJ/mol 44.4 kJ/mol 52.7 kJ/mol Chem 210 Final: Mastering Chem 2023 With C omplete Updated Solution 3.50 × 104 J - answerCalculate the energy that is required to change 50.0 g ice at -30.0°C to a liquid at 73.0°C. The heat of fusion = 333 J/g, the heat of vaporization = 2256 J/g, and the specific heat capacities of ice = 2.06 J/gK and liquid water = 4.18 4 J/gK. 1.31 × 105 J 2.14 × 104 J 1.66 × 104 J 3.50 × 104 J 6.59 × 103 J 67.7 kJ - answerHow much energy must be removed from a 125 g sample of benzene (molar mass= 78.11 g/mol) at 425.0 K to liquify the sample and lower the temperature to 335.0 K? The f ollowing physical data may be useful. ΔHvap = 33.9 kJ/mol ΔHfus = 9.8 kJ/mol Cliq = 1.73 J/g°C Cgas = 1.06 J/g°C Csol = 1.51 J/g°C Tmelting = 279.0 K Tboiling = 353.0 K C and D only - answerA hypothetical substance has a melting point of −10°C and a boil ing point of 155°C. If this substance is heated from 2°C to the gas at 155°C, which of the following would be used in the calculation: 1. specific heat capacity of the solid 2. heat of fusion 3. specific heat capacity of the liquid 4. heat of vaporization 5. specific heat capacity of the gas Chem 210 Final: Mastering Chem 2023 With C omplete Updated Solution The solid will sublime into a gas - answerA substance has a triple point at −24.5 ∘C and 225 mmHg. What is most likely to happen to a solid sample of the substance as it is warmed from −35 ∘C to 5 ∘C at a pressure of 2 10 mmHg? Nothing (the solid will remain as a solid). The solid will sublime into a gas. The solid will melt into a liquid. 29.8 kJ/mol - answerThe vapor pressure of a substance is measured over a range of temperatures. A plot of the natural log of the vapor pressure versus the inverse of the temperature (in Kelvin) produces a straight line with a slope of −3.58×103K. What is t he enthalpy of vaporization of the substance? 29.8 kJ/mol 2.32×1023kJ/mol 0.431 kJ/mol 294 kJ/mol lithium iodide, LiI sodium fluoride, NaF potassium bromide, KBr - answerFive different substances are given to you to be dissolved in water. Which substanc es are most likely to undergo dissolution in water? lithium iodide, LiI sodium fluoride, NaF potassium bromide, KBr benzene, C6H6 hexane, C6H14 Dipole -dipole: C2H5OH HF Ion-dipole forces:
