Covalent bonds - Study guides, Class notes & Summaries

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

The attractions between atoms within a molecule of NH3 are best characterized as A. hydrogen bonds B. ionic bonds C. polar covalent bonds D. London (dispersion) forces E. ion-dipole forces Correct Answer-polar covalent bonds R(g) + 2T(g) ⇌ 2X(g) + Z(g) The reaction mixture above is at equilibrium at 298 K. The value of the equilibrium constant for the reaction is 16 at 298K. If R(g) , X(g) and Z(g) each have an equilibrium concentration of 2.0 M, what is the equilibrium concentrati...

True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False...
