Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds Explanation: Water is a chemical molecule with unique properties such as a low melting point, ability to dissolve other substances, and strong adhesion and cohesion, as stated in this question.
WebQuestion 1 1 pts Hydrogen bonds are weaker than covalent bonds. During PCR, two DNA strands are separated by breaking hydrogen bonds during the denaturation step. WebAlthough hydrogen bonds are significantly weaker than covalent bonds, with typical dissociation energies of only 15–25 kJ/mol, they have a significant influence on the physical properties of a compound. Compounds such as HF can form only two hydrogen bonds at a time as can, on average, pure liquid NH 3.
