Question

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

The correct explanation for why twice as much hydrogen as oxygen is formed in the decomposition of water is:

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

In the chemical reaction, 2 H₂O (water) decomposes into 2 H₂ (hydrogen gas) and O₂ (oxygen gas), reflecting the ratio of atoms in the water molecule.
