Calculate the oxidation number of the underlined atoms in the following species. ul(N)H_(2)OH,[ul(Co)(NH_(3))_(5)Cl]Cl_(2),(ul(N_(2))H_(5))_(2)SO_(4),ul(Mg)_(3)N_(2)

Calculate the oxidation number of the underlined atoms in the followin

1.	Calculate the oxidation number of the underlined atoms in the following species. ul(N)H_(2)OH,[ul(Co)(NH_(3))_(5)Cl]Cl_(2),(ul(N_(2))H_(5))_(2)SO_(4),ul(Mg)_(3)N_(2)
Answer» Solution :Following calculations are CARRIED out in SHORT. x represents the O.N. of the underlined atom. `NH_(2)OH:x+(+)xx2+(-2)+(+1)=0` `:.x=-1` `[Co(NH_(3))_(5)Cl]Cl_(2):x+(0)xx5+(-1)+(-1)xx2=0` `:.x=+3` `(N_(2)H_(5))_(2)SO_(4):{(x)xx2+(+1)xx5}xx2+(-2)=0` `x=-2` `Mg_(3)N_(2):3(x)+(-3)xx2=0` `:.x=+2`
