Question

In the decomposition of water, why is twice as much hydrogen as oxygen formed? (1 point)

Answer 1

In the decomposition of water, the ratio of hydrogen to oxygen is 2:1 because water has the chemical formula H2O, which means a single molecule of water consists of two hydrogen atoms and one oxygen atom. When water is decomposed, each molecule is broken down into its constituent atoms, resulting in the formation of two hydrogen atoms and one oxygen atom. Thus, twice as much hydrogen as oxygen is formed.
