What happens when the temperature of a solid reaches its melting point? A) the kinetic energy reaches its maximum amount.
B) the kinetic energy breaks the bonds between atoms.

Which statement best describes the he properties of iconic compounds ?

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
