Hydrogen bonding is necessary for bonding carbon to oxygen. forming double-stranded dna molecules. decreasing the boiling point of liquids such as water. causing van der waals interactions.

How have the greenhouse gasses increased from the year 2000 to 2018

Who examines and coordinates the cleanup of polluted sites?

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.
