Calculate the enthalpy change when \( 50 \mathrm{~mL} \) of \( 0.01 \mathrm{M} \mathrm{Ca}(\mathrm{OH})_{2} \) reacts with \( 25 \mathrm{~mL} \) of \( 0.01 \mathrm{M} \mathrm{HCl} \). Given that \( \Delta H_{\text {neut }}^{\circ} \) of a strong acid and strong base is \( 140 \mathrm{kcal} \) equivalent.
(A) \( 14.0 \mathrm{cal} \)
(B) \( 35 \mathrm{cal} \)
(C) \( 10.0 \mathrm{cal} \)
(D) \( 7.5 \mathrm{cal} \)
