Show Answer

Answer:

Correct Answer: C

Solution:

$ \overset{*}{\mathop{N}},O_2 $ ; $ x-4=0 $ ; $ x=+,4 $

$ H\overset{*}{\mathop{N}},O $ ; $ 1+x-2=0 $ ; $ x=+1 $

$ \overset{*}{\mathop{NH_3}}, $ ; $ x+3=0 $ ; $ x=-3 $

$ {{\overset{*}{\mathop{N}},}_2}O_5 $ ; $ 2x-10=0 $ ; $ 2x=10 $ ;

$ x=\frac{10}{2} $ ; x = 5.
