Why the dipole moment of Co2 is zero and that of H2O is 1.85D?

Answer/ explanation :

In CO2 molecule, the angle between O-C-O is 180, therefore, when the oxygen atom attracts the electron pair towards itself, then it becomes partially negative and the carbon atom becomes partially positive. The bonds in O=C=O are pointing opposite each other and the bond dipoles cancels each other thereby making it zero.

The dipole in O-H bonds cannot cancel out and that is why water has an overall molecular dipole of 1.85D.

CO2 is a linear molecule, so the dipoles are symmetrical. The dipoles are equal in both magnitude but are differ in point facing opposite directions.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
