Exam |55 Questions and Answers
Hydrogen Bond - -The bond responsible for cohesion and adhesion of water molecules.
-Nonpolar covalent bond - -The bond between two oxygen atoms in O2
-Polar covalent bond - -The bond between H and O atoms within one molecule of water.
-Ionic Bond - -The bond between elements with very different electronegativities (such as
sodium cation and chlorine anion)
-When solutes such as sodium and chloride are dissolved in water, water molecules
surround the solutes creating a ______ around them. - -Hydration shell

temperature.
Saturated fatty acids contain more hydrogen than unsaturated fats having the same
number of carbon atoms.
Saturated fatty acids may be a component of phospholipids in membranes.
