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

Answer 1

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 atoms for every one oxygen atom, which is why twice as much hydrogen is formed compared to oxygen during the decomposition of water.
