1.	S_(4)N_(x) in vapour state is subjected to decompoition totally to get octaatomic sulphur vapour and nitrogen gas . Under similar conditions the volume of products is 2.5 times to the reactants. Deduce the molecular formula of the nitride of sulphur. Calculate the weight percentage of nitrogen.
Answer» Solution :The decompoition is given as `UNDERSET((G))(S_(4)N_(x))to underset((g))((1)/(2))S_(8) +underset((g))((x)/(8))N_(2)` By analysing the given data , 1+x=5:x=4 MOLECULAR formula =`S_(4)N_(4)` Weight percentage of NITROGEN `(4xx14)/(4(32+14))xx10=30.43%`
