Transcription of this question: 3.Dinitrogen monoxide, NZO, causes depletion of ozone in the stratosphere.(a)(b)Outline why ozone in the stratosphere is important.Different sources of NZO have different ratios of 14N: “N.0)(ii)State one analytical technique that could be used to determine the ratioof 1 ‘N: ISN.A sample of gas was enriched to contain 2% by mass of 15N with the remainderbeing IAN.Calculate the relative molecular mass of the resulting Nzo.(iii)Predict, giving two reasons, how the first ionization energy of ISN compares withthat of 14N.(c)Suggest why it is surprising that dinitrogen monoxide dissolves in water to give aneutral solution.
