While working in the lab, you accidentally mix two liquids together. The beaker the two liquids were mixed in gets very hot. This is a reaction, and specifically an reaction.
A) chemical, exothermic
B) physical, exothermic
C) chemical, endothermic
D) physical, endothermic.

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.
