Hydrogen atoms are twice the size of oxygen atoms.
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.

This is because each water molecule (H₂O) is composed of two hydrogen atoms bonded to one oxygen atom, leading to the formation of twice as much hydrogen gas (H₂) as oxygen gas (O₂) during the decomposition of water.
