The  number  of  O2 ( oxygen)   molecules  that are produced  from splitting of two molecules  of water is 1  molecule  of oxygen ( answer D)


Explanation

A molecule   -  is a group of two or more  atoms  held together  by a chemical bond.

In  the  reaction of splitting  of  2   molecules  of  H2O  yield 1  molecule  of O2.


  • 1  molecule of O2  is made up  of two atoms of  Oxygen  held  by  double  covalent bond.  
  • The two  oxygen atom  form molecule  by sharing  two valence electrons.
