The correct response is:
There are two atoms of hydrogen and one atom of oxygen in a water molecule.
This explains why, in the decomposition of water (H₂O), twice as much hydrogen gas (H₂) is formed compared to oxygen gas (O₂). Each water molecule consists of two hydrogen atoms and one oxygen atom, leading to the production of twice the volume of hydrogen as oxygen during the decomposition process.
