Dipole Study guides, Class notes & Summaries

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 depends on the linearit...

Electric Dipole Moment Correct Answer Neutral molecule with uneven charge distributions (partial charges) e.g. H2O Diffusion Correct Answer Movement of molecules from areas of high to low concentrations e.g. Volatile Perfume distributing through the air Osmosis Correct Answer Diffusion of WATER through a membrane e.g. Aquaporins (biological proteins) Hydrophilicity Correct Answer "Water Loving" e.g. Charged ions that interact with the Electric Dipole Moment in water. (Soluble) Hydr...

intermolecular forces correct answers forces that hold molecules to other molecules (not bonds within molecules) ion-ion interaction correct answers occurs between ions, with opposite charges attracting and like charges repelling ion-dipole interaction correct answers occur between ions and polar molecules, where the ion is attracted or repelled to a partial charge in the polar molecules (includes interactions between water and dissolved ions) dipole-dipole interaction correct answers o...

HOMEWORK EXAM 1 CHEM 142 QUESTIONS AND ANSWERS GRADED A Is there an attraction between two neutral helium atoms? Explain in detail why or why not. Be sure to include any evidence you have for your claim and how this supports your reasoning. Yes; 2 helium atoms can be attracted because the electrons in the electron cloud are freely moving. This leads to one of the atoms becoming an instantaneous dipole, this will then induce a dipole on the other atom. The opposite partial charges will a...

TBR Physics II Exam Questions & Answers 2024 *Electrostatics & magnetism* - ANSWER- Coulomb's law - ANSWER- Electric & gravitational forces - ANSWER- When voltage is applied across a wire, a current flows Imagine *e-'s go up V stairs* - ANSWER-*Electrons* move from *lower to higher voltage* (opposite to current "+ charge") The current makes electrons flow into the wire and out of the wire (equalling each other), so the net charge on a wire will not change. The *net charge i...
