Nitrogen oxides such as N2O and N2O5 are present at low concentrations in smog, in part because of their reactivity. Balance the chemical equations by adding the missing coefficients.

(a) The conversion of N2O to NO2 in the presence of oxygen
(b) The decomposition of N2O5 to NO2 and O2

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
