Consider the following equations : 2Fe2+ + H2O2 → xA + yB (in basic medium) 2MnO4- + 6H+ + 5H2O2 → x’C + y’D + z’E (in acidic medium) The sum of the stoichiometric coefficients x, y, x’, y’ and z’ for products A, B, C, D and E, respectively, is ………..

(i) 2Fe2+ + H2O2 → 2Fe3+ + 2OH- (ii) 2MnO4- + 6H+ + 5H2O2 → Mn2++ 5O2 + 8H2O So sum of (x + y + x1 + y1 + z1) = 2 + 2 + 2 + 5 + 8 = 19

Consider the following equations :

2Fe²⁺ + H₂O₂ → xA + yB (in basic medium)

2MnO₄^- + 6H⁺ + 5H₂O₂ → x’C + y’D + z’E

(in acidic medium)

The sum of the stoichiometric coefficients x, y, x’, y’ and z’ for products A, B, C, D and E, respectively, is ………..

(i) 2Fe²⁺ + H₂O₂ → 2Fe³⁺ + 2OH^-

(ii) 2MnO₄^- + 6H⁺ + 5H₂O₂ → Mn²⁺+ 5O₂ + 8H₂O

So sum of (x + y + x¹ + y¹ + z¹) = 2 + 2 + 2 + 5 + 8 = 19
