Question

When a water sample is taken from the sea, what will be the ratio of the atoms released upon ionization of a water molecule from the sample?

• A. 1 molecule of oxygen and 2 molecules of hydrogen
• B. 1 atom of hydrogen and 2 atoms of oxygen
• C. 1 molecule of hydrogen and 2 molecules of oxygen
• D. 1 atom of oxygen and 2 atoms of hydrogen

Answer 1

The correct option is D

1 atom of oxygen and 2 atoms of hydrogen

Water's molecular structure is constant irrespective of the source. It is represented by $H_{2}O$. So one molecule of (H_2O) will always consist of 2 atoms of hydrogen and 1 atom of oxygen.
