College chem! phosphoric acid, h3po4, is a triprotic acid found in some soft drinks such as coca-cola (shown in the photo at the start of this chapter) where it adds a
touch of tartness to the beverage. write equations for its stepwise ionization in water. include states in your answer.

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.
