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

Responses

Hydrogen atoms are twice the size of oxygen atoms.
Hydrogen atoms are twice the size of oxygen atoms.

Some oxygen gas escapes the reaction, and hydrogen gas is conserved.

There are two atoms of hydrogen and one atom of oxygen in a water molecule.
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.

The correct response is: There are two atoms of hydrogen and one atom of oxygen in a water molecule.

This is why, during the decomposition of water (H₂O), twice as much hydrogen gas (H₂) is produced compared to oxygen gas (O₂). Each water molecule contains two hydrogen atoms and one oxygen atom.
