Question

Identify Y and G Y + H2SO4 -----> G + H2O * ​

Answer 1

Answer:

Correct option is

C

x=8,y=4,z=4

To balance the number of iodine atoms, HI is multiplied with 2.

Iodine is oxidized. Its oxidation state changes from −1 to 0. Net increase is +2.

Sulphur is reduced. Its oxidation state changes from 6 to −2. Net decrease is 8.

To balance the net increase and net decrease in the oxidation number, factor 4 is used. Thus, coefficients of HI and I

2

are multiplied by 4.

To balance oxygen atoms, four water molecules are required on the right.

Thus, x=8, y=4 and z=4.
