Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?

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.
