Why do you think that the enthalpy of vaporization for water is so much larger than the enthalpy of fusion? Hint: Think about intermolecular forces.

(b) Why is the magnitude of this value so much larger than the heat of vaporization of water (AH°vap = 41 kJ/mol)? * Choose one: A. Less energy is needed to form attractive forces between water molecules than to break H-H and O-O bonds and form H-O bonds. O B. More energy is needed to form attractive forces between water molecules than to break H-Hand O-O bonds and form H-O bonds. o C. Less energy is needed to break attractive...
i need help with this a little bit. The standard molar heat of formation of water is –285.8 kJ/mol.b) Why is the magnitude of this value so much larger than the heat of vaporization of water (ΔH°vap = 41 kJ/mol)?Choose one:A. More energy is needed to break attractive forces between water molecules than to break H–H and O–O bonds and form H–O bonds.B. More energy is needed to form attractive forces between water molecules than to break H–H and O–O bonds and...
& Why do you think more energy is required to separate two xenon atoms than is required to separate particles involved, are stronger than gravitational forces, which depend on the mass of the particles. two neon atoms? Remember that electrical forces, which depend on the number and charges of the 9. Why do you think that energy is required to separate two water molecules in an anti-parallel configuration, but in a parallel configuration, water molecules repel each other? (Remember that...
Why aren't heavier elements much larger than lighter elements? Why aren't heavier elements much larger than lighter elements? Larger nuclear forces pull the electrons into closer orbits. Larger gravitational forces pull electrons into closer orbits. The larger positive charge in the nucleus pulls the electrons into closer orbits. Larger magnetic forces pull electrons into closer orbits.
Which of the following statements is FALSE? O When a substance melts, some - but not all-of the intermolecular forces are disrupted O When a substance evaporates, all of the intermolecular forces are disrupted O A compound with stronger intermolecular forces will have a higher boiling point The enthalpy of sublimation is less than the enthalpy of vaporization but more than the enthalpy of fusion O The enthalpy of vaporization for a compound is greater than the enthalpy of fusion...
Why do you think Mexico’s Off-trade volume is so much higher, and growing faster than other Latin American countries?
q 2 and 4 please! Question 2 Which of the following compounds will hydrogen bond with water (H20)? Select all that apply. Cl2 CC14 CH20 NH3 SCI2 Question 3 Which of the following will have the lowest boiling point? Ne OKr O Ar o Не Question 4 Which of the following statements is FALSE? O A compound with stronger intermolecular forces will have a higher boiling point When a substance melts, some - but not all- of the intermolecular forces...
Why do you think the outer planets are larger and more gaseous than the inner planets? Is this typical of other solar systems that are being discovered by the Kepler Telescope? Give some examples to support your answer.
Which compound (water, acetone, ethanol, hexane, decane, or 1-decanol) do you think will be the least volatile and explain why. You must discuss intermolecular forces in your explanation.
HELP!! Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection. Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
