Expert Answer:

Selenium will be reduced, So its reduction can be written as:
Se to the power of plus 4 end exponent plus left parenthesis 4 minus straight a right parenthesis straight e rightwards arrow Se to the power of straight a plus end exponent
straight n equals 4 minus straight a
left parenthesis where space straight n space is space valence space factor right parenthesis
space space space space space space space space Cr to the power of plus 2 end exponent rightwards arrow Cr to the power of 3 plus end exponent space plus space straight e
Meq. space of space SeO subscript 2 equals Meq. space of space CrSO subscript 4
0.0509 cross times straight n cross times 12.53 equals 0.1 cross times 1 cross times 25.52
straight n equals 4

straight a equals 0

Thus space redox space change space is colon space Se to the power of plus 4 end exponent plus 4 straight e rightwards arrow Se to the power of 0
