If the reaction is at equilibrium, what direction will the reaction shift if \( \mathrm{NH}_{3} \) gas is added? View Available Hint(s) The reaction will shift to produce both reactants and products. The reaction will shift to produce products. The reaction will remain unchanged. The reaction will shift to produce reactants.

\( \_ CaO + \ldots HCl \rightarrow CaCl _ { 2 } + \ldots H _ { 2 } O \)

A metal is considered reactive if it easily loses electrons to achieve a stable octet. Would you prefer metal that readily loses electrons? How is this related to the metal's ionization energy? Would it be better for the metal to have high or low ionization energy?

\( - Mg ( OH ) _ { 2 } + \ldots HCl \rightarrow MgCl _ { 2 } + \ldots H _ { 2 } O \)
