$2Na(s) + 2HCl(g)\,\, \to \,\,2NaCl(s) + {H_2}(g),$$\Delta H = - 152\,kcal$ For the reaction $Na(s) + \frac{1}{2}C{l_2}(g)\,\, \to \,\,NaCl(s),\,\Delta H = $ .....$kcal$
$(I)$ Only $C$ react with $0.10\, M\, HCl$ to give $H_2(g)$
$(II)$ When $A$ is added to solution of the other metal ions, metallic $D$ is formed but not $B$ or $C$
