Consider the following equations :
2Fe2+ + H2O2 $\to$ xA + yB
(in basic medium)
2MnO4- + 6H+ + 5H2O2 $\to$ 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 ______.
Answer (integer)
19
Solution
2Fe<sup>2+</sup> + H<sub>2</sub>O<sub>2</sub> $\to$ 2Fe<sup>3+</sup> + 2OH<sup>–</sup>
<br><br>2MnO<sub>4</sub><sup>-</sup> + 6H<sup>+</sup> + 5H<sub>2</sub>O<sub>2</sub> $\to$ 2Mn<sup>2+</sup> + 8H<sub>2</sub>O + 5O<sub>2</sub>
<br><br>$\therefore$ x + y + x' + y' + z' = 19
