Iam having a really hard time with this subject.

now that you have learned about balancing equations, explain to me why you are only allowed to change to numbers out front of bonds, and not the small numbers behind the elements (subscripts).

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.
