Balance the following equations:

straight I subscript 2 plus HNO subscript 3 space rightwards arrow space space NO subscript 2 plus HIO subscript 3 plus straight H subscript 2 straight O


Solution
2 HNO subscript 3 space rightwards arrow space space space space straight H subscript 2 straight O space plus 2 NO subscript 2 plus left parenthesis straight O right parenthesis                          ...(1)
            straight I subscript 2 plus 5 left parenthesis straight O right parenthesis space space rightwards arrow space space space straight I subscript 2 straight O subscript 5                                  ...(2)
     straight I subscript 2 straight O subscript 5 plus straight H subscript 2 straight O space rightwards arrow space space 2 HIO subscript 3                                    ...(3)
Multiplying equaton (1) by 5 and adding these three equations.
 open square brackets 2 HNO subscript 3 space rightwards arrow space straight H subscript 2 straight O space plus space 2 NO subscript 2 plus space left parenthesis straight O right parenthesis close square brackets cross times space 5
    straight I subscript 2 plus 5 left parenthesis straight O right parenthesis space rightwards arrow space space straight I subscript 2 straight O subscript 5
straight I subscript 2 straight O subscript 5 plus straight H subscript 2 straight O space rightwards arrow space space space 2 HIO subscript 3
