Let apostrophe straight s space assume space the space formula space of space NxH subscript straight y
NxH subscript straight y stack rightwards arrow straight x over 2 with blank on top straight N subscript 2 space plus space straight y over 2 straight H subscript 2

The space equation space becomes comma
straight x over 2 cross times 40 plus straight y over 2 cross times 40 space equals 80
therefore space straight x space plus space straight y space equals space 4 space................... left parenthesis 1 right parenthesis

Now space the space present space straight H subscript 2 space reacts space with space straight O subscript 2 space to space form space water
straight H subscript 2 space plus space 1 half straight O subscript 2 space rightwards arrow with blank on top space straight H subscript 2 straight O
straight x over 2 cross times 40 space plus space 40 minus 10 straight y space equals 30

Now space thr space remaining space volume space will space be space the space combination space of space straight N subscript 2 space and space straight H subscript 2
therefore space 2 straight x space minus straight y space equals space minus 1 space.................................. left parenthesis 2 right parenthesis
After space solving space left parenthesis 1 right parenthesis space and space left parenthesis 2 right parenthesis space we space get comma
space space space space space space space straight x space plus up diagonal strike space straight y end strike space equals space 4
space space space space space space 2 straight x space up diagonal strike negative straight y end strike space equals space minus 1
space space space space space minus negative negative negative negative negative negative
space space space space space space space 3 straight x space space space space space space space space equals space 3
therefore straight x equals space 1 space
straight x space plus space straight y space equals 4
1 space plus space straight y space equals space 4
therefore space straight y space minus space 3

therefore space straight N subscript straight x straight H subscript straight y space equals space NH subscript 3
