In the balanced chemical reaction
`IO_(3)^(ө)+al^(ө)+bH^(ө)rarrcH_(2)O+dI_(2)`
`a, b,c`, and `d`, respectively, correspond to

Options

A. 5,6,3,3
B. 5,3,6,3
C. 3,5,3,6
D. 5,6,5,5

Answer

A

Explanation

`overset(+5)(I)O_(3)^(-)+overset(-1)(I)+H^(+)rarrH_(2)O+I_(2)^(0)`
Decrease in O.N of I =5 per atom
Increase in O.N of I = 1 per atom
`IO_(3)^(-)+5I^(-)+H^(+)rarrH_(2)O+3I_(2)`
`IO_(3)^(-)+5I^(-)+6H^(+)rarr3H_(2)O+3I_(2)`.
