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

Responses

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.
Hydrogen gas has two atoms, and oxygen gas has one atom.

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

Hydrogen atoms are twice the size of oxygen atoms.

The correct response is:

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

In a water molecule (H₂O), there are two hydrogen (H) atoms for every one oxygen (O) atom, which results in the formation of twice as much hydrogen gas compared to oxygen gas during the decomposition of water.
