Answer: ICl. ICl and Br2have similar masses (~160 amu) and therefore experience similar London dispersion forces. ICl is polar and thus also exhibits dipole-dipole attractions; Br2is nonpolar and does not. The relatively stronger dipole-dipole attractions require more energy to overcome, so ICl ...
When the dependency on vibe was removed in#316, the simulation picked up sound effects for checkboxes, buttons, and sliders. @amanda-phetsaid: I generally don't like UI sounds when there are "silent" interactions, especially the most important pedagogical interactions. In other sims, we've us...
The increase in melting and boiling points with increasing atomic/molecular size may be rationalized by considering how the strength of dispersion forces is affected by the electronic structure of the atoms or molecules in the substance. In a larger atom, the valence electrons are, on average, fa...
