Question
In the decomposition of water, why is twice as much hydrogen as oxygen formed?
(1 point)
There are two atoms of hydrogen and one atom of oxygen in a water molecule.
☐ Hydrogen gas has two atoms, and oxygen gas has one atom.
☐ Hydrogen atoms are twice the size of oxygen atoms.
Some oxygen gas escapes the reaction, and hydrogen gas is conserved.

The correct explanation for why twice as much hydrogen as oxygen is formed in the decomposition of water is:
**There are two atoms of hydrogen and one atom of oxygen in a water molecule.**
This means that for every molecule of water (H₂O) that decomposes, two hydrogen atoms are released for every one oxygen atom.
**There are two atoms of hydrogen and one atom of oxygen in a water molecule.**
This means that for every molecule of water (H₂O) that decomposes, two hydrogen atoms are released for every one oxygen atom.
