Question

NH3 o2=N2 H2O balance it

Answer 1

ANS-------

(a)NH3+(b)O2---->(c)NO+(d)H2O

a=c, we see N=N=1

Take a=1, c=1

3a=2d, we see H=3=------>H=2

take 3a=2d

    a=1 so,

  d=3/2

2b=c+d

2b=5/2

 b=5/4  

PUT VALUES ABOVE  a,b c d,   TO make equation

4*(NH3+ 5/4O2----->NO+  3/2H2O)

4NH3+ 5O2------> 4NO  +  6 H2O

THANKS TO SEE

Answer 2

NH3 + O2 = N2 + H2O

4NH3 + 3O2 = 2N2 + 6H2O

Hope it helps...
