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...
