For the redox reaction:
MnO subscript 4 superscript minus space plus space straight C subscript 2 straight O subscript 4 superscript 2 minus end superscript space plus space straight H to the power of plus space space space rightwards arrow space space space space Mn to the power of 2 plus end exponent space plus space CO subscript 2 space plus space straight H subscript 2 straight O
the correct stoichiometric coefficient of space space space space space MnO subscript 4 superscript minus comma space space straight C subscript 2 straight O subscript 4 superscript 2 minus end superscript comma space space straight H to the power of plus are ? 

Solution

The correct stoichiometric coefficient of space space space space space space space space space MnO subscript 4 superscript minus comma space space straight C subscript 2 straight O subscript 4 superscript 2 minus end superscript comma space space straight H to the power of plus are 2, 5, 16
the balanced equation is,
space space 2 MnO subscript 4 superscript 2 minus end superscript space plus space 5 straight C subscript 2 straight O subscript 4 superscript 2 minus end superscript space plus space 16 straight H to the power of plus space rightwards arrow space space space 2 Mn to the power of 2 plus end exponent space plus space 10 CO subscript 2 space plus space 8 straight H subscript 2 straight O
