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 atoms are twice the size of oxygen atoms. Hydrogen atoms are twice the size of oxygen atoms. 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.
There are two atoms of hydrogen and one atom of oxygen in a water molecule. Therefore, when water is decomposed, twice as much hydrogen as oxygen is formed.
so each H2O molecule yields half an O2 molecule but a whole H2 molecule
That is correct. Each water molecule (H2O) yields half an oxygen (O2) molecule and one whole hydrogen (H2) molecule when it is decomposed.
