Name: Date: 1. The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond dep...

Dipole Moment Correct Answer The difference in charge between atoms in a water molecule Water Molecules Interact With Each Other Through _______ Correct Answer Hydrogen Bonds Why is water liquid at room temperature? Correct Answer Because the hydrogen bonds within it are constantly breaking and reforming on different molecules (moving around) Shell of Hydration Correct Answer The oxygen atoms in water will orient themselves towards positively charged ions in water, the hydrogen atoms wi...

What is the difference in the properties of a solid, liquid, or gas reflect the strengths of the attractive forces between the molecules that make up each phase? - ANSWERintermolecular forces What are the examples of intermolecular forces? - ANSWERdispersion, dipole-dipole, hydrogen bonding Dipole-dipole interactions are attractive forces that act between ______ molecules. - ANSWERpolar Polar molecules have permanent dipoles. The positive end of one permanent dipole is attracted to the ...

Covalent Bond Correct Answer-Form between non-metals and share electrons Nonpolar covalent bond Correct Answer-Has no net charge and share electron equally between atom Polar covalent bond Correct Answer-One atom is slightly more positive than the other and unequally share electrons Electronegativity Correct Answer-The net ability of an atom to attract an electron from another atom. An atom with high electronegatvity is an electron Correct Answer-Acceptor An atom with low electron...
