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...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...
