N-factor for the following reaction is FeS_(2)toFe_(2)O_(3)+SO_(2)

1.	N-factor for the following reaction is FeS_(2)toFe_(2)O_(3)+SO_(2)
Answer» 8 9 10 11 Solution :`overset(+2)(FE)overset(-1xx2)/(S_(2))tooverset(+3xx2)(Fe_(2))overset(-2xx3)(O_(3))+overset(+4-2xx2)(SO_(2))` `underset(2x=4)(2FE^(2+))overset(0)tounderset(2x=6)(Fe_(2)^(3+)+2e^(-)]n=(2)/(2)=1` `{:(underset(2x=-2)(S_(2)^(2-))toundersetunderset(2x=18)(2x-8=0)(2SO_(2))+10e^(-)]n=10` Total n factor `=10+1=11`
