Also, the combustion of dinitrogen (1) oxide produces brown fumes of nitrogen IV oxide.
Finally, when dinitrogen (1) oxide and oxgen are both heated with copper, residual nitrogen gas is left with dinitrogen (1) oxide while no residual gas is left with oxygen.
T½=18.72days
therefore t¾=18.72+½ of 18.72
we have 18.72+9.36=28.08days
