In the decomposition of water, why is twice as much hydrogen as oxygen formed?(1 point) Hydrogen gas has two atoms, and oxygen gas has one atom.

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.

Hydrogen atoms are twice the size of oxygen atoms.
