In the equation for the reaction of water decomposition under the influence of direct current, the sum of the coefficients is …
Explanation of the solution to the problem: in order to solve this problem, it is necessary to draw up an equation for the chemical reaction of the decomposition of water under the influence of a constant electric current (electrolysis): 2H2O => 2H2 + O2.
Thus, it turns out that there is a coefficient 2 in front of the water, 2 in front of the hydrogen molecule, and 1 in front of the oxygen molecule, therefore, the sum of the coefficients is 2 + 2 + 1 = 5.
