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...

Intermolecular forces and how they affect physical properties /purification techniques: dipole-dipole, electrostatic, hydrogen, ion, london, - Answer-*dipole-dipole*: polar covalent molecules such as aldehydes and ketones. positive and negative end. polar molecules must be close together for force to be significant. weaker than ion-dipole forces; increase with polarity of molecule. *electrostatic*: occur between charged species, cations and anions, and are responsible for very high MP and B...
