space space space NH subscript 3 space space plus space space 3 Cl subscript 2 space space space leftwards harpoon over rightwards harpoon space space NCl subscript 3 space plus space 3 HCl space space space space space space minus increment straight H subscript 1 space space space space......... space left parenthesis 1 right parenthesis

space space space straight N subscript 2 space space space end subscript space space plus space space space 3 straight H subscript 2 space space space space leftwards harpoon over rightwards harpoon space space space 2 NH subscript 3 space space space space space space space space space space space space space space space space space minus increment straight H subscript 2 space space space space.......... left parenthesis 2 right parenthesis

space space space straight H subscript 2 space space space space space space space end subscript plus space space space space Cl subscript 2 space space space space leftwards harpoon over rightwards harpoon space space space 2 HCl space space space space space space space space space space space space space space space space space space space space increment straight H subscript 3 space space space........... space left parenthesis 3 right parenthesis

Now space multiplying space eq space left parenthesis 2 right parenthesis space by space bevelled fraction numerator 1 over denominator 2 space end fraction space space and space eq space left parenthesis 3 right parenthesis space by space bevelled 3 over 2

space space space 1 half straight N subscript 2 space space space end subscript space space plus space space fraction numerator space 3 over denominator 2 end fraction straight H subscript 2 space space space space leftwards harpoon over rightwards harpoon space space 3 NH subscript 3 space space space space space space space space space space space space space space space space space 1 half left parenthesis negative increment straight H subscript 2 right parenthesis space space space space.......... left parenthesis 4 right parenthesis

space space 3 over 2 space straight H subscript 2 space space space space space space space end subscript plus space space space 3 over 2 space Cl subscript 2 space space space space leftwards harpoon over rightwards harpoon space 3 HCl space space space space space space space space space space space space space space space space space 3 over 2 increment straight H subscript 3 space space space........... space left parenthesis 5 right parenthesis

Adding space eq space left parenthesis 1 right parenthesis space and space eq space left parenthesis 4 right parenthesis

up diagonal strike space space space NH subscript 3 space end strike space plus space space 3 Cl subscript 2 space space space leftwards harpoon over rightwards harpoon space space NCl subscript 3 space plus space 3 HCl space space space space
space space
space space 1 half straight N subscript 2 space space space end subscript plus space space fraction numerator space 3 over denominator 2 end fraction straight H subscript 2 space space space leftwards harpoon over rightwards harpoon space space up diagonal strike 3 NH subscript 3 space end strike space space
