B) nitrogen In the cases of \(NH_3\), \(H_2O\) and \(HF\) there must be some additional intermolecular forces of attraction, requiring significantly more heat energy to break the IMFs. A. diethyl ether Within a vessel, water molecules hydrogen bond not only to each other, but also to the cellulose chain that comprises the wall of plant cells. When something boils, you're not actually breaking any of the covalent bonds, so that doesn't explain anything Order the following solutions from lowest to highest pH\mathrm{pH}pH : (i) 0.10MNaClO0.10 \mathrm{M} \mathrm{NaClO}0.10MNaClO. B) C6H6 A) definite shape and volume For H2O, Hfus = 6.01 kJ/mol and Hvap = 40.67 kJ/mol, AB= H= (1.00 mol)(18.0 g/mol)(2.03 J/g-k)(25K) = 914 J =.91 kJ In nonane we have these As the chain length (numbers of carbons) increases A) Metallic bonds only The van der Waals attractions (both dispersion forces and dipole-dipole attractions) in each will be similar. The hydrogen atom is then left with a partial positive charge, creating a dipole-dipole attraction between the hydrogen atom bonded to the donor and the lone electron pair of the acceptor. The vapor pressure will be higher (more gas molecules are present) B) ionic Branching in higher weight alkanes makes it impossible to predict BP solely on the basis of MW. Well, we don't actually B) XeF4 Methylchloride, CH3Cl 50 1.9 C) indefinite shape, but definite volume At room temperature, the lighter alkanes E) a saturated solution. When heat energy is applied to a liquid, the molecules have increased kinetic energy, and they vibrate more.
