What happens to a confined gas at a constant temperature when the volume is reduced to 1/2

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

The empirical formula of a compound is ch2o and its mass is 120 amu/molecule, what is its formula?

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.
