1.	Indicate in which of the following processes nitrogen is recuced ?
Answer» `NH_(4)^(+) rarrN_2` `NO_(3)^(-) rarrNO` `NO_(2) rarr NO_(2)^(-)` `NO_(3) rarrNH_(4)^(+)` SOLUTION :Decrease in oxidation number is REDUCTION. a) `overset(-3)(NH_4^(+))rarroverset(0)(N_2)` b) `overset(+5)(NO_3^(-)) rarroverset(+2)(NO)` c) `overset(+4)(NO_2)rarroverset(+3)(NO_2^(-))` `overset(+6)(NO_3)rarroverset(+3)(NH_(4)^(+))`
