The correct sequence of the oxidation state of underlined elements is Na_(2)[ul(Fe)(CN)_(5)NO],K_(2)ul(Ta)F_(7),Mg_(2)ul(P)_(2)O_(7),Na_(2)ul(S)_(4)O_(6),ul(N)_(3)H

The correct sequence of the oxidation state of underlined elements is

1.	The correct sequence of the oxidation state of underlined elements is Na_(2)[ul(Fe)(CN)_(5)NO],K_(2)ul(Ta)F_(7),Mg_(2)ul(P)_(2)O_(7),Na_(2)ul(S)_(4)O_(6),ul(N)_(3)H
Answer» <P>`+3, +5, +5, +2.5, -(1)/(3)` `+5, +3, +5, +3, +(1)/(3)` `+3, +3, +5, +5, -(1)/(3)` `+5,+5, +3, +2.5,+(1)/(3)` Solution :`Na_(2)[""ul(Fe)(CN)_(5)NO]:+2+x+5(-1)+0=0rArrx=+3` `K_(2)ul(Ta)F_(7):+2+x+(-7)=0rArr x=+5` `Mg_(2) ul(P)_(2)O_(7):+4+2x+(-14)=0 RARR x=+5` `Na_(2)ul(S)_(4)O_(6):+2+4x+(-12)=0` or `4x=10 rArr x=+2.5` `ul(N)_(3)H:3x+1=0 rArr x=-(1)/(3)`
