Question

9. The oxidation state of the most electronegative atom in each of the product is H2 + O2 + H2O2 + H2O​

Answer 1

The products of the reaction are hydrogen peroxide (H2O2) and insoluble barium sulphate (BaSO4). The most electronegative element here is oxygen. The oxidation state of oxygen in H2O2 is -1, and it is -2 in BaSO4.

Answer 2

Here most electronegative atom is O2

In oxygen oxidation state. = -2 (Total = -4)

In H202, Oxidation state of Oxygen = -1 (total = -2)

I'm H20 oxidation state = -2
