Awater bug can walk on water because of the of the water molecules

1. surface tension

2. cohesion

3. adhesion

4. polarity

The answer is surface tension. The water has an inward attraction because there are no molecules above it (I mean water, at least), and the legs of water bugs repel water, hence, they walk on water.

Hope this helps!

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

a) the particles of the chair are strongly held together.
