The mass ratio of hydrogen to oxygen obtained by electrolysis of water is () A.2:1 B.4:8 C.1:16 D.1:8

The mass ratio of hydrogen to oxygen obtained by electrolysis of water is () A.2:1 B.4:8 C.1:16 D.1:8

Write the chemical equation for the electrolytic water reaction, and then calculate the sum of the relative molecular masses of the reactants and the resultant, respectively
2H2O energization

.

2H2↑+O2↑
36 4 32
According to the mass ratio of the substance equal to the ratio of the relative molecular mass sum, it can be known that the mass ratio of hydrogen to oxygen is 4:32 1:8
Therefore, D.
