Question

what kind of bond holds together a water (h2o) molecule? o a) polar covalent bond o b) familial bond o c) ionic bond o d) sticky bond

Explanation:

In a water ($\ce{H2O}$) molecule, the bond between hydrogen and oxygen is a polar covalent bond. Oxygen is more electronegative than hydrogen, causing a partial charge separation in the $\ce{H - O}$ bond, which is characteristic of a polar covalent bond. Ionic bonds involve complete electron transfer, familial bond is not a chemical bond type, and "sticky bond" is not a recognized chemical bond.

Answer:

A) Polar covalent bond
